:confused:I am still learning and am pretty new the DTG world. I have the white shirts down. Thought that I was making head way on darks. I have had some success. But then I think I am doing the same steps and I get peeling and cracking. But know I feel like I am back at the beginning. I get my supplies from Colman & Company. I have a Kiosk. How do I know if I have too much pretreatment or too little, do I need to dilute the pretreatment, how much pressure when I press? Should the shirt be totally dry after the 10 - 15 sec of pressing? Do I need to let the pretreat soaking before I roll/brush it or do I roll/brush it right away. I am very frustrated and am tired of wasting money trying to get it right. Are the steps the same for t-shirts and sweatshirts?

Any help would be GREATLY appreciated. I am ready to throw in the towel.


:(:(

Ok so too much pretreat will make it peel, and too little will make it fade? Do Ineed to dilute the pretreat?

I am pressing for 2:40 @ 345 with light pressure. Does that sound right?

You should not dilute white pretreatment when using it for dark shirts. You should also make sure you are using the right cover sheets when heat pressing - uncoated parchment or butcher paper for pretreatment - silicone coated parchment paper for drying finished prints.

Hi,

I print between 200 & 500 dark shirts a week. The best pre treat is from Innovative Garment Solutions. No dilution is needed.

Best practise is pre press the shirt for 10 seconds @ 165c high pressure. Then pre treat, press with non silicone paper for 10 seconds very light pressure, normally just the weight of the heat platen. Remove paper and press 15 seconds high pressure. Works every time for me.

Hope this helpd.

OK, I had much better results. I did several test area and washed twice with much better results no peeling. I do notice that I have some white poking through in red lettering. Is that do to too much pressure or to much heat. I have a knight clam press and am using very little pressure. Just the weight of the top plate resting on the shirt. There is not enough pressure for the press to release on it's own. For temp I am using 345 for 2:40. Tahnk for your help!!

Hi Julie
Which method worked best? did you dilute the pretreatment or no?
Thanks

I did both. I have some already diluted so I did it both ways. There was not that much of a difference. It was only diluted by about 30%.

Try hovering the heat press over the shirt with no protectant sheet for the first drying time (2.5 min @330 deg) then cover image and heat press ad usual!
Well I am still having the white show through my red ink after pressing. Also after a 3rd wash the red is coming off and the white is showing through even more. Why can I not get this!!!!! Not sure if it matters but I am doing a hoodie.

What is the content of the hoody? This can make a big difference.

What print resolution are you printing at and how many layers, this can also have a big impact on your results. I will try to help if you can give me the exact process you are using for pretreating, printing and curing as all three of these factors need to be right to get good results. Let me know these and I will try to help you get better results :)
