I printed a sample for a customer, 10 colors wet on wet.
Base white double stroke 150 thin mesh.
Roller
Top colors 225 thin mesh.
Customer is complaining that it's too thick and rough.
They must be comparing to shirts printed in India where they press every shirt after it's printed and they area very smooth.
How high can I go with mesh counts to get a thinner print and good coverage on a black T shirt?

Looks at if your not clearing the screen. You are printing Virus ink?

Rutland M3

What white ink are you using? 2 things are going on. 1: the ink is not clearing thru the screen ( show the stroke down or thin down the ink with a little chino) 2: you are over flashing and bubbling the ink?

Maxie , What base white are you running? The epic quick has been a game changer here as far as the hand with our large retail clients. Also, With all the supernice printable inks available why are you struggling with m3. Again not known for its soft hand, prinability. That ink is a long bodied product.
160 Base- sharp 70/90/70 to clear the screen.. I would consider the epic quick
230-305 all over print colors- even using the M3

Thanks, could be some of the above.
Over flash, could definately be a problem.
White I think is Rutland Silky White, I'll check tomorrow.
We cannot get everything here (in Israel).
I import the M3.
I think I should really try the 305 but will I get enough coverage? It will be smoother.

I don't know what fabric content the shirt is, but if 100% cotton a discharge under base may solve the issue of the rough print with that many colors wet on wet. We do 80% base, and 20% pre-mix white to get a brighter base but not enough white pigment load that the plastisol colors don't adhere.
Another product is the Magna Killer Base, which is a water base HSA white made for printing plastisol top colors that we've had some good results with when tested side by side with a plastisol base, get more vibrant and smooth top colors (limited testing) - https://www.magnacolours.com/product/magnaprint-killer-base/ (https://www.magnacolours.com/product/magnaprint-killer-base/)
I think that a 305 you won't get enough ink for the colors to pop, but you never know until you try. However it's costly to try on a 10 screen job when you may be able to just switch to a different base and get the results you are looking for.

I second the Magna killer base. We’ve found it works great and creates the smoothest underbase we’ve ever had. Just make sure you don’t have bleeding issues.

I'm no expert on WOW printing but I've had nice results using some QCM softee base on some of the higher build up inks and printing through a 305 mesh has worked for me to reduce the build up even more and still give a smooth print.
