The aim is to create a precise and durable (but always limited) matrix that allows the ink to pass through the screen in a controlled and quality manner onto the substrate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Emulsions are sensitive to UV light and require a light source to harden and form a matrix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During the process, the screen printing emulsion is applied to the screen mesh, forming a uniform, thin layer. After drying, the screen is then exposed to light with a photolitho, which contains the design\/image to be printed. The photolitho is placed between the light source and the emulsion in order to block the light in the desired areas. As a result, the light hardens the exposed areas of the emulsion and the remaining area, protected from the light, does not harden. After exposure to light, the screen is washed with water, which removes the unhardened emulsion, creating the design\/image of the photolitho.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-container-core-column-is-layout-80351644 wp-block-column-is-layout-flow\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\">\n<div class=\"wp-block-buttons is-layout-flex wp-container-core-buttons-is-layout-0f8319cb wp-block-buttons-is-layout-flex\" style=\"margin-top:0;margin-bottom:var(--wp--preset--spacing--70)\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-100 has-custom-font-size is-style-outline has-small-font-size is-style-outline--1\"><a class=\"wp-block-button__link has-secondary-color has-custom-blue-fica-background-color has-text-color has-background has-link-color wp-element-button\" href=\"https:\/\/fica-oc.pt\/en\/blog\/screen-printing-2\/photolitho-1-is-the-only-concern\/\" style=\"border-style:none;border-width:0px;border-radius:50px;padding-top:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40)\"><strong>SEE ARTICLE ON PHOTOLITHOGRAPHS<\/strong><\/a><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">At this stage, the screen is ready for printing.

Each one has its own characteristics and the most suitable applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diazo-based screen printing emulsions are bi-component, made up separately of the emulsion (which is not sensitized) and diazo, which is a chemical compound that is sensitive to and activated by light. Prior preparation is required to mix the two components.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Due to their composition, photopolymer emulsions are ready to use and no components need to be added. In this sense, they are easier to use than diazo-based emulsions, as they require no prior preparation. Also due to their composition, they are more sensitive to light and therefore generally require shorter exposure times and less margin for error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dual cure emulsions combine the properties of a diazo emulsion and a photopolymer. They are bi-component, made up of emulsion and diazo, but the emulsion is pre-sensitized. This means that after mixing (prior preparation is also required to mix the two components) a mixture with two doubly sensitized elements is created.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Photopolymer and Dual Cure emulsions are capable of producing detailed and sharp images. They are known for their high resistance to abrasion as well as solvents, which makes them ideal for printing on a variety of substrates. Both can be water and solvent resistant (suitable for various types of inks), while diazo is generally water or solvent resistant and not both.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-container-core-column-is-layout-ff4bb270 wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">All types of screen printing emulsion have different variations and brands available on the market, each with its own characteristics and specific properties. The choice of screen printing emulsion will depend on the type of material to be printed on, the ink used, the complexity of the design, as well as exposure and washing conditions. However, personal preference will always weigh more heavily. Once you've found the right light exposure time, with a specific emulsion, and you've had positive printing results, you'll still want to work with the same solution.

Potassium bichromate is a chemical compound that was once widely used as a component in screen printing emulsions. However, potassium bichromate is toxic and carcinogenic, and its use has been discouraged and even banned in many countries. Screen printing emulsion manufacturers have been replacing it with other safer and less environmentally harmful emulsions, creating emulsions that do not contain chromates in their composition.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignwide is-layout-constrained wp-container-core-group-is-layout-f2c53e4d wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading alignwide has-text-align-center has-medium-font-size\" id=\"existem-emulsoes-menos-nocivas-ao-ambiente-e-saude\" style=\"font-style:normal;font-weight:700\">Are there any emulsions that are less harmful to the environment and health?<\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-cb8105e7 wp-block-columns-is-layout-flex\" style=\"padding-right:0;padding-left:0\">\n<div class=\"wp-block-column is-layout-flow wp-container-core-column-is-layout-ff4bb270 wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-left wp-block-paragraph\">It's a difficult question to answer when it comes to chemical compositions.

Dual cure emulsions, on the other hand, can have a slightly longer shelf life after mixing, but no more than 6-8 weeks. Finally, photopolymer emulsions have a longer shelf life compared to diazo and dual cure emulsions, and can last several months or even more than a year if stored properly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, it is important to follow the manufacturer's instructions and check the expiry date indicated on the packaging of each screen printing emulsion, as they may have different expiry dates depending on the type or manufacturer. In addition, shelf life can be affected by external factors such as temperature and humidity. It is therefore important to store emulsions properly and to check the quality of the emulsion before each use.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-bottom is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-top:var(--wp--preset--spacing--30)\">\n<div class=\"wp-block-group has-secondary-color has-custom-blue-fica-background-color has-text-color has-background has-link-color wp-elements-0639b0c6a8193018fbc17b476b8798df is-layout-constrained wp-container-core-group-is-layout-59c09e46 wp-block-group-is-layout-constrained\" style=\"border-radius:20px;margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40);padding-top:var(--wp--preset--spacing--50);padding-right:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\">\n<h4 class=\"wp-block-heading\" id=\"conselho\" style=\"font-style:normal;font-weight:700\">Council<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-style:normal;font-weight:500\">Every time you start using a screen printing emulsion, write the date on the packaging.

The concept, and positive point, of a screen is that it can be reused. Which means you can remove the emulsion and re-emulsify it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This also means that, no matter how resistant it is, once we start using the screen, the emulsion will eventually lose resistance and come off little by little. However, if you look after it properly, you can make hundreds of prints with the same matrix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Screen printing emulsion (dual cure) lasts a long time if you follow a few tips and adopt good practices. In the case of large print runs, you may have to make more than one exposure. In our experience, an engraved screen is capable of reproducing up to 500 units (this may vary).<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-container-core-column-is-layout-130f6bea wp-block-column-is-layout-flow\" style=\"padding-top:0\">\n<div class=\"wp-block-group has-secondary-color has-custom-red-fica-background-color has-text-color has-background has-link-color wp-elements-7c73f77debcb4b05b477d81db061d63c is-layout-constrained wp-container-core-group-is-layout-4fa477f7 wp-block-group-is-layout-constrained\" style=\"border-radius:20px;margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40);padding-top:var(--wp--preset--spacing--60);padding-right:var(--wp--preset--spacing--60);padding-bottom:var(--wp--preset--spacing--60);padding-left:var(--wp--preset--spacing--60)\">\n<h4 class=\"wp-block-heading\" id=\"conselho-6\" style=\"font-style:normal;font-weight:700\">Council<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-style:normal;font-weight:500\">Paint should always be cleaned immediately after use. First remove the excess paint with a spatula. Then, using a super-soft sponge moistened with water (for water-based paints), run it over the canvas without rubbing, so that the paint comes off more easily. Wash the sponge and go over the paint areas again, rubbing gently. Repeat these steps until the paint has come off.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-style:normal;font-weight:500\">Whenever you use adhesive tape, it is preferable to choose a solvent-free one. Ideally, the adhesive tape should be removed immediately after using the canvas, otherwise, over time, it can be very difficult to remove the adhesive tape and it will leave traces stuck to the canvas. In this case, use a damp sponge to remove the tape, rubbing moderately, but it may not come off.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-style:normal;font-weight:500\">If, during use, small dots of emulsion start to come out that don't interfere with the design, you should block them with adhesive tape on the side of the canvas in contact with the substrate.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:80px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignwide has-background is-layout-constrained wp-container-core-group-is-layout-ce40c9cd wp-block-group-is-layout-constrained\" style=\"background-color:#eaeaeaad;padding-top:var(--wp--preset--spacing--50);padding-right:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\">\n<h2 class=\"wp-block-heading alignwide has-large-font-size\" id=\"conclusao\" style=\"font-style:normal;font-weight:700;text-transform:uppercase\">Conclusion<\/h2>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-3d41d305 wp-block-columns-is-layout-flex\" style=\"margin-top:0;margin-bottom:0;padding-top:var(--wp--preset--spacing--40);padding-right:0;padding-bottom:var(--wp--preset--spacing--40);padding-left:0\">\n<div class=\"wp-block-column is-layout-flow wp-container-core-column-is-layout-ff4bb270 wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">In conclusion, the screen printing emulsion plays a key role in the process of engraving a matrix, (on the screen printing screen), when UV light is blocked during exposure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The choice between emulsions, taking into account exposure times, resistance, type of ink, type of light source (exposure unit) and experience, can be important in guaranteeing print quality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The dual cure emulsion guarantees high quality abrasion resistance and fine detail. At the same time, it has greater exposure latitude, which makes it more user-friendly when engraving the matrix, especially if you're a beginner. However, prior preparation and a shorter lifespan are drawbacks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Photopolymer emulsion has a longer shelf life and requires no prior preparation, which makes it more attractive for those who don't record regularly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of the three types, diazo emulsion has the greatest number of drawbacks. But it can easily be used for matrices with less detail, as long as it is suitable for the type of solvent used in the paint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Correct storage, following expiry dates, and adopting responsible practices and other advice are imperative. By focusing on resistance, proper storage and responsible practices, it is possible to ensure consistent emulsion performance, which is fundamental to success in the process.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-container-core-column-is-layout-ff4bb270 wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Light sensitivity, correct preparation (when necessary) and the choice between different types of emulsion contribute directly to the quality and durability of the matrix, positively influencing the final print. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the biggest challenges when using any screen printing emulsion is the exposure time. We stress that any aspect can alter the exposure time. Starting with the emulsion itself, which can be more or less sensitive to light.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The type of light can mean different distances between the light source and the screen. The power and level of UV will also affect the length of exposure time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The type of photolitho, and the quality and level of opacity of the photolitho, will influence the exposure due to its ability to block out light.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If we add the number of layers of emulsion (1, 2 or more layers), we add another factor to the equation, which will directly influence the duration of the exposure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a detailed understanding of these elements and the implementation of good practices are essential to achieving consistent, quality results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Proper use in the printing process, especially when cleaning, is extremely important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, we would like to stress that we are not concluding that the screen printing emulsion we use is the best. However, during our journey and experiences, it was the emulsion that guaranteed the best results for the type of projects we have.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-text-align-left has-regular-font-size wp-block-paragraph\" style=\"padding-top:var(--wp--preset--spacing--20);padding-bottom:var(--wp--preset--spacing--50);font-style:normal;font-weight:500\">We remember that experience and experimentation are important for finding the best solutions for the characteristics of each person's project.<\/p>\n<\/div>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignwide is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-columns alignfull is-layout-flex wp-container-core-columns-is-layout-1a9244c7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-columns has-secondary-color has-custom-red-fica-background-color has-text-color has-background has-link-color wp-elements-6f9bfb19732da3a5b5b8f87d890765de is-layout-flex wp-container-core-columns-is-layout-1a9244c7 wp-block-columns-is-layout-flex\" style=\"border-radius:10px\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\" id=\"telas-com-gravacao\" style=\"font-style:normal;font-weight:700\">Screens with engraving<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-style:normal;font-weight:500\">At FICA Oficina Criativa, in addition to selling screen printing canvases, we also offer an exhibition\/engraving service.
