White Ink (Post Wash Peel) Ok we are in a funny situation. We have the pretreatment down to perfection. One coat with 1440x1440 (we have a 4880 print head so the dots are smaller, lower resolutions look choppy). It is smooth, solid, and the color coat couldn't look better.
The problems we are facing are after multiple washings, corners start to peel. Its not major, just very small peel ups from the corners but if you pull them it will pull a bigger piece and break off.
We have done over 30 different prints with different settings. We get the best wash tests from the following.
We are using a Blazer Express (which has the 4880 Print Head) with Hanes Tagless and Beefy T shirts.
1440x1440 White
1440x720 Color (tried 720x720 but didnt come out as good texture/color wise)
4 mins pressed at 330 with 100 PSI
Underbase Settings
100 Strength
100 Light
100 Dark
10 Choke
Underbase Black Checked
All shirts were washed 10 times, cold water, inside out, dried on delicate.
Some Notes:
With our testing we discovered the following things provided better wash results even though they tend to go against the recommended norm.
We found underbasing black was necessary because if you didnt then it just created more corners which then peeled.
We found higher pressure (100-115 PSI) worked a lot better than the lower PSI settings (25, 35, 40, etc). For lights, the lower PSI works better but for a white underbase, it was higher.
Like I said above, we also found it necessary to underbase 1440x1440 or it was choppy. I read in another post this was because the 4880 Print Head had a smaller dot size then most other print heads.
I am at a loss really for what it could be. We tried different shirts both combed and open ended, different amounts of pretreat, different print resolutions both color and white, different tempatures, different cure times, different pressures, etc, etc. Like I said, we literally tried over 30 different prints, all with different settings, and washed them all.
I am really starting to wonder if its just how it is or if there is some combination of settings we just haven't found yet.
Has anyone been able to get dark shirts that look great after the initial print to still look great after many washings? |
