You will barely see the ink + no adhesion at all.

 

Yikes... I see...

Would you know about CMYK on white shirts without white ink or pretreat?

Does that work?

 

It improve adhesion wash fastness, colors, have a look to image armor website.

but on the new F2000 it seems it yield poor result based on some recent posts.

 

i do not pretreat white shirts with the brother gt3, i have a r3000 based dtg printer as well using dupont inks and in my opinion you cannot get a decent print on whites without pretreat, lay to little ink and the print is faded, add more to make the colours pop and the ink starts bleeding.

 

My rule of thumb is that if there is no white ink to be printed on the shirt, you are not likely to need to pretreat the shirt.

 

that depends on the inkset and printer used.

 

have you looked into fbx-100 its a new pretreat that's very versatile and easy to use, white great white and washability. i would take a look into it before you decide not to try white ink.

 

You don't have to pretreat white garments, but if you do the results are actually extremely improved. The image attached here are printed with Image Armor LIgHT and the left is not treated, while the right is treated.

Wash ability is improved, color intensity is improved and detail improved. Do you have to PT? No, but.......

I believe this image was a 100% poly, but the results are still impressive with 100% cotton shirts.

 

Wow that photo is changing my mind about pre-treat.... Thanks for showing us!! Was that with a white underbase, or without?

 

I forgot to mention that Image Armor LIgHT formula can be printed with or without a white under base. This makes a great tool for light colored shirts. Many pretreatment will not "work" as well if just a CMYK image is printed on the normal pretreatment. The image will look awesome after printed but wash durability is not good. So, you can get some great prints if you use your noodle and play (I.e. One pass white highlight and CMYK with no under base on lighter colored shirts with still great wash ability.

 

Jgabby, actually if you were referring to IA LIGHT with the Epson it works great.... You just can't use a DARK formula on a light or white shirt as what happens I mentioned above with poor wash ability.

 

Without an under base......on polyester.

 

While you do get more vibrant colors on white using the proper pre treat, for most customer orders it's not needed. Yes you can see the difference and the customer will always choose the pre treated one if you show th both. Even with that being said, most of the time I find pre treating white not worth the extra cost and labor. 99% of the customers are very happy with a non pre treted cmyk print on a white tee.

 

what inkset and printer ? i use a gt3 i do not pretreat whites, regular dupont for epsons does need it for cmyk, believe me i have tried with two different rips and it doesnt work, perhaps i should try firebird in the r3000 ? i love the gt3, i hate the ink price.

pm me if you dont mind, im the other side of the pond and as tight as a ducks arse

 

I have had very good luck not pretreating white shirts with Dupont ink for my old Sprint and now with Epson Ink for my Epson F2000.

I always do a two pass print job.

Now with my Epson and with NeoRip I am do the color strength @ 75% with a 20% color boost. Cutting back the color strength stops the bleed and the two passes allows the first layer to set a little allowing the 2nd layer to have the colors pop very nice...

I also print this one for most shirts (white and light colored) that I print for our grandchildren....and they get the real abusive wash tests from my daughters...regularly washed with jeans...

I do agree that when I have pretreated white shirts and printed...the prints are crisper and look nice...but when I do the wash test I get about the same results and I prefer to be able to offer my customers lower cost solutions and save me on labor and materials....

just my 2cents

 

i used to run a diy 1150 with dupont, two passes were okish and sellable, that was with the epson driver, i have tried an awful lot of time and ink to make the r3000 work with cmyk no pretreat, no matter what i do it looks crap, if anyone can give me the magic settings i will try them (i have ekprint and acrorip) at the moment time is my enemy as im working at almost full capacity with the gt3, i do not have time to pretreat lights, but im desperate to save money!

 

with my old Sprint, epson based printer and EK print 3.4 verion, I used to do two passes at level 2 setting...seemed to work for me...
