My wife and i started this project and were doing well, i am graphic designer and art graphics specialized for 25 years, but once a mug box finish and start other begin this problem, i think the mug quality (thin coated finish) is poor and if this it, there is way to avoid this issue?

1- I will try lower the pressure and heat (actually 395F and 180 secs, 300F min, we insert the mug when reach 460F, low the temp and rise again)

2- Wrap another paper to protect the print paper

3- Low the time too to 160 secs


I wonder if anyone in this forum has experienced the same problem and if you could really have a solution to avoid wasting 30 mugs.

What i did try:

Change the transfer paper, same result

Change pressure (lower and upper), same result

Change time and heat (lower and riser), same result


TECH SPECS

EPSON WORKFORCE 30
(Name removed by Admin) DYE SUB INKS
CHINA PRESS MUG HEATER
STANDARD TRANSFER PAPER (i think is china branded)
MUG FROM CHINA

Why too much china?, well, is because the provider offer.

Before that we sublimate 72 mugs without this kind of problem, we overcome other problems: right print colors (use icc profiles from i don't know where i downloaded) print size of the mug (we discover that the heat element is not the best and decide not to reach the mug borders), and press problem.

Well , THANK YOU VERY MUCH FOR THE KIND ATTENTION

First thing I'd do would be try different mug suppliers. You show one mug is perfect whilst another is poor, looks like poor quality mugs imo. Also, a known brand if paper would help. Make sure you're using good heat tape but I think your problems could be the mug coating.

We can't help with the inks you've mentioned due to Sawgrass licence restrictions but this could well be contributing to your problems as well.

Thanks for your quick response Justin, i think this mug package comes with bad quality, the tape was bought in amazon, but the problem is only with this mug, not the other 4 packages.

Justin i like to know if i wrap it with double paper can damage the teflon blanket, i think too, that if use double paper i had to increase the time and low the pressure, i am right?

[ernestomac]

Ok, i made another test, no tape, less pressure. time and temp, double paper, same results! bad quality coated mug! thanks!

I have no idea what suppliers you have in Venezuela, but if you want to try high quality mugs, look for 'Rhino' or 'Orca' coating.

[ernestomac]

Since you mention that, when I buy I asked were of high quality and I sold AAA, a friend told me they were not AAA but A. He says because they are not pure white. I do not know what to say since you mentioned the cups by the type of finish and i think it should be.

Heat.

You using WAAAAYYYYY to much heat. thats why you have paper marks and heat tape marks. coating actually melt

try much, much lower temperature. 495F is about 260C!!! all you need is 175-180C

[ernestomac]

I'm sorry is 395F! not 495!!, but last one i used 380F that is 193C and 160 secs and bad results, do you think i should try less than that? 175C is about 347F, what about time? the same 180 secs?

[Paul]

First test i would do on 175c for 280sec.
