How do you identify a serigraph?
Silkscreens, also called serigraphs, are stencil prints. They are called silkscreens because the stencil process is completed with the aid of a screen. Color is forced through the stencil in layers on the paper. Serigraphs or silkscreens will be easily identifiable by spotting a layering of colors on top of each other.

How long do screen printing screens last?

How do you tell if water-based ink is cured?
As with curing plastisol inks, you can use temperature strips or an infrared thermometer to check the temperature of the ink as it comes off of the dryer. You also will want to perform a wash test of a trial print to be sure that your water-based ink has been properly cured./span>
Can you dry emulsion with a hair dryer?
I’ve done this many times and it works just fine. I’ve needed to burn a screen in a hurry and I’ll coat 1-1, then dry it with a hair dryer for 5 minutes each side, burn image, wash out, then dry with hair dryer again, then put on the exposure table for 3-4 minutes to cure fully.
How do you know if plastisol is cured?
The ultimate and definitive test to determine if plastisol inks are properly cured is a wash test. Wash the garment in hot water with a strong detergent. Generally it will take from 5-10 washings to fully test the cure, but if the ink is seriously under-cured, the print will show deterioration after only 1-3 washings.
How long does it take for plastisol ink to cure?

Can you cure plastisol with a heat gun?
If a heat gun is the method you’re using to cure garments, make sure you’re being careful because it’s a high chance that the inks will not hit its cure temperature. For plastisol ink, apply the heat gun to the garment until it’s dry to the touch. Heat guns are not a good option for printing water-based./span>
Are plastisol inks dangerous?
Plastisol inks are made from polyvinyl chloride that reacts with other chemicals to form dioxins. Dioxins are highly toxic chemical compounds that are harmful to health. However, plastisol inks are safe to use if handled with care./span>
Is photo emulsion toxic?
Its toxicity is mainly localized to the screenprinter when it is cured by the heat and water vapor can carry the formaldehyde fumes into the shop area to be breathed in. Depending on how good of a ventilation system a shop has, that’s the most toxic part of the screenprinting process. emulsion remover is non-toxic./span>
Are water-based inks environmentally friendly?
Water-based ink is an environmentally friendly printing option. Water-based inks are non-toxic and do not contain any lead or heavy metals, nor do they contain o-zone depleting chemicals like chlorofluorocarbons (CFC’s) or other volatile solvents./span>
Is plastisol eco friendly?
Plastisol ink is made by mixing PVC resin and plasticizer together. Water-based inks are much more eco-friendly because they are completely PVC free and, hence the name, water-based; i.e., they have a solvent base consisting of water. They’re about as environmentally-responsible as you can get in this business./span>
Why is ink bad for the environment?

Is screen printing bad for the environment?
The truth is that screen printing is a demanding and historically toxic environment in which to work. As safe as wearing ventilation masks and goggles are, using traditional cleaning chemicals isn’t a “green” process, and many long term printers deal with severe health problems down the road as a result./span>
What is plastisol made of?
Plastisols are pastes composed of fine polyvinylchloride (PVC) particles suspended in liquid plasticizer. Plastisols sometimes include small amounts of extenders, stabilizers, pigments and fillers. Typical PVC to plasticizer ratio is 50/50 by weight.
