Discharge is the process of chemically removing the pigment in the T-shirt and then printing on the raw material that is left with regular screen printing ink. It basically removes the need for an under print. It's a little pricey and when we experimented with it the shirt material that had the chemicals put on it wore out much quicker than the rest of the garment. If you don't have a "huge" under print area stick with the under print.Elevate(r) said:Can someone tell me a bit about this? I'm researching it as an option for getting some tees printed.
Pricing verses screen printing on tees?
Printers that do this in So Cal (san diego)?
Any info would be great.
It basically bleaches the dye out of the shirt.. so removing the dark ink from a shirt. You can either leave it that way (if you want a light pattern on a dark shirt) or print more colors on top with regular ink.Is discharge printing only for light ink over dark shirts or also for dark ink over light shirts?
Actually it depends on the brand of discharge you use. I have many customers printing very bright and vibrant colors (reds, yellows, blues, ect.) on black and other dark shirts. The fabric definitely plays a major roll in determining how well the garment will discharge. For example, American Apparel brand usually discharges much better than a Gildan.The colors will not be majorly vibrant as the raw color of cotton is natural. If you add yellow pigment to the discharge and print on a black shirt the color will be yellow with a greenish hue to it.
For light colors, non-discharge water based inks work best.You can add dark ink pigments and print on lighter colors to get the no feel print.
This also depends on the brand of ink. Matsui International has developed an exceptional discharge base that is not very expensive. You can get the base for about $35 a gallon and the agent is about $25 a quart. A quart of the agent (the discharge activator) works for about 3 gallons. So, your final price (before you add color pigment) is roughly $43 a gallon. Plus, it's water based ink...so you don't need any chemicals to clean the screens.Discharge printing is more expensive than regular plasticol printing. The base and activator are real expensive. About $200 per gallon compared to about $35 for a gal of regular ink.
Excellent, thank you for that. Most of my designs tend to be detail heavy with lots of fine lines so my screens are usually 160 or 180 mesh and rarely anything less. I can design for a slightly lower mesh count.That sounds about right. I use 158 with the Matsui discharge. I wouldn't go any higher than that.
Huh, that's interesting. Almost a do-it-yerself discharge print. VERY CREATIVE! I like it!I did a discharge print with out buying any of those products like discharge base or agent. Heres how you do it.
Buy a Clorox bleach pen. Squeeze it out on the screen. Do like any other print and you got ... Discharge softhand effect!
The Clorox is thick enough not to run and spread and gives the same discharge effect. Try it and see.
