Pic 1: close up showing an oil like stain/mark on the P of the word JAP.
Pic 2: pic of the whole logo on the tee (just out of washing machine to see if it would remove the marks)
Pic 3: the tee shirt sub paper after printing, showing no marks?




Method - Tee shirt: place sub paper on top of garment, place clean (new) sheet of white a4 printer paper around the edges, and place a Teflon sheet over the printable area, press with medium pressure at the usual settings (the image results are fine)



I also had the same issue with a phone case print this morning, but further to these 2 jobs this morning, I also successfully printed the same type of tee shirt with a different Jap design, with no issues. For this I did as above, but placed a clean (new) sheet of a4 paper over the job, instead of a Teflon sheet

It would suggest there is a mark either on your teflon sheet or on your platen. Give both of them a thorough clean and try again (Use the same garment as before).

Make sure you clean the base platen as well. If that is rubber then increase the temp up to 200 and press for 2 minutes with nothing in (that will burn off any excess ink).


Lastly, not sure why you put a piece of A4 paper in between the teflon and the dye sub paper. I can not see any benefit to that, but then if it works for you then keep doing it

Hi,

Thanks for your help & suggestions, I will look in to them. I have actually just ordered some new Teflon sheets as mine are quite old, and had cleaned the platen before I began to press this morning. ( any cleaning methods or materials recommendations?) My Teflon sheet was probably dirty in all fairness though. I wasn't aware of the attention to the bottom rubber sheet, so will look at that.

Regarding the use of paper, I probably didn't explain properly. I put paper around the edge of the logo just as extra protection for the white material that is not being printed. then a Teflon sheet over the printable area (the logo) The next job I just used a white paper sheet (instead of Teflon) and didn't get the same marks, so it probably was the Teflon sheet.
With the phone i just used a white paper sheet again, and still got stains.

Thanks again for the help, its much appreciated.
