Among the greatest questions surrounding is: it is environmentally friendly? While the standard technique may not be, there are choices which make screen printing exceptionally helpful for the environment. Learn more
When it comes to screen printing kit, there are two various types of inks that can be utilized: plastisol ink and water-based ink. It utilizes a polyvinyl chloride (PVC) base, as opposed to water-based ink, which is exactly what its name suggests, a water-based ink with pigments suspended within it.
Moreover, the print result is impacted by the colour of the garment. For instance, utilizing a purple coloured t-shirt may alter the appearance of the ink colour. Water-based inks also do not work well on all materials and are much better matched for much shorter run orders. For printing soft prints onto dark coloured garments there is a screen printing method that utilizes discharge water-based inks.
Benefits of utilizing water-based screen printing:
Water-based inks are very beneficial since of their adaptability and capability to print a large range of products. They can be utilized to print onto non-textile products like sticker labels, stationery, and canvas, as well as garments such as Tee shirts, polo’s, hoodies, sweatshirts, caps, tote bags, coats, aprons and practically any other garment that can be put on a platen to be screen printed. Water-based inks works well with cotton, polyester and poly-cotton blends.
In the screen printing industry, the term ‘hand’ describes how soft a print feels to the touch. Plastisol inks, for instance, are popular for the optimum or hand that they provide. Water-based inks result with very little or soft hand onto printed garments, just like direct to garment (DTG) digital printing that is almost seamless to the touch. An added advantage with water-based inks is that they can be ironed over, while plastisol prints can not due to the fact that the iron can easily melt the PVC into the ink.
Water-based prints produce colours that are frequently far more vibrant than plastisol prints. After correct curing, a Tee shirt or other printed garment with a water-based print will be likely to outlive the material on which it was printed. Due to the very little hand of water-based prints, large and comprehensive styles printed onto a garment will feel light and thin, while the exact same style printed using plastisol inks will be much heavier since of the density of the ink layers.
Garments which are printed utilizing water-based inks are likewise most likely to be far more comfortable to use. Because water-based inks permeate the printed material, rather than sit on top like with plastisol inks, skin under the printed garment can breath simpler.
Water-based ink is an ecologically friendly printing alternative. After a printing run, screens and printing devices can be washed off using conventional water, and it is safe to decrease the drain unfiltered. Water-based inks are non-toxic and do not consist of any lead or heavy metals, nor do they contain o-zone depleting chemicals like chlorofluorocarbons (CFC’s) or other unpredictable solvents.
PVC based inks and the environment:
Plastisol is a PVC based ink which is a carcinogen understood to trigger major risks in the environment and to be harmful for people. Plastic is damaging the natural world and its ecosystems while having extreme effects on life and the future sustainability of our world. As ‘greener’ efforts start (and have already begun!) influencing the cumulative awareness of humankind and markets start turning away from plastic in as lots of ways as possible, this likewise consists of the preference of screen printing inks that individuals purchase to use.
PVC inks, like plastisol, are not drain pipes safe. Printers utilizing plastisol needs to resort to harmful and environmentally damaging chemicals to break down plastisol from printing equipment and screens. Specifically developed filters need to be set up on drains to capture PVC particles. Lots of commercial printers are thorough in taking safety measures, however unfortunately, many do not.
Plastisol is popular and enjoyed by printers since it is relatively inexpensive and very well fit for mass productions and big run orders because it does moist and clog printing devices. Plastisol never ever dries, it remains in a semi-liquid state up until it is treated at a temperature level until the water in the ink has totally vaporized, leaving behind just the pigment colours.
Water-based ink advantages:
‘ Soft hand’ prints
Environmentally friendly
Lovely, vibrant colours
Outstanding for printing onto lighter-coloured garments
Water-based downsides:
Can not print onto darker garments
Inks are impacted by the garment colour
Not well fit for printing onto all materials
Plastisol inks are much better for larger print runs.
