So I had a rip design which I did in black and white t-shirts. The black t-shirts came out nice and detailed, I used separation studios. But when I did a 4 color process on white tees, the image printed very dark and oversaturated. Also loss alot of details that were white. Why did this happen?

how many colors was it on the dark? just another which was white underbase? plastisols? same screens both jobs (minus the white underbase)?

If this was seped properly with a white base for darks then you have to print the white base even on white. For CMYK prints I print a white base even on white for consistent prints

yeah and i didn't know if there was a white highlight sep that was just knocked out or not printed......

Does Seperation Studio also do CMYK seperations not just simulated?

i'm not sure because i don't use it.

you might want to start a separate thread and ask the whole forum.

Sorry for the late response, for the 4 color job I didn't separate any colors, all I did was print the 4 cmyk channels no editing. The only print I used separation studio for was for the black shirts. Also I don't think its possible to separate 4 color process image with separation studio since theres no black channel. Unless you can create a black channel in separation studio is that possible?

I used different screens for both jobs. For the dark shirt I got it down to 4 colors and the 5th screen for the white underbase. So total 5 screens to make the simulated process image.

Maybe it is too dark on white because you didn't compensate properly your dot gain on press.

If you use the 4 CMYK channel without any adjusment I am not surprise.

 

[Slee410]

How exactly am I suppose to adjust? I enhanced the photo for better print quality and set the lpi to 61. What else needs to be done?

 

[sben763]

If your doing a CMYK print most process inks have a profile to apply to the file. I use a rip to print so all the dot gain controls are done there. Before printing with the rip I never used any dot gain controls or adjustment besides the ink profile with great results but every shop is different.

 

[Slee410]

Ic now, hmm.. so from illustrator I printed the image using accurip though..

 

[sben763]

What brand of CMYK ink do you have. Look and see if they have a profile. The profile will tell illustrator how to output the colors to accurip

 

[Slee410]

Gotcha, I am using ryonets cmyk brite inks. So if I'm understanding correctly, I need to use the color profile and accurip together? But for simulated process no color profile needed, just separation studio?

 

[sben763]

Yes. They have the color profiles right on their page for the CMYK process inks. I don't use seperation studio but I would guess it has the profile embedded in the program as it uses it own ink set.

 

[Slee410]

I see, one last question, for dark shirts I am using ryonets process inks but it doesn't have blacks, so pretty much I can only do photo images on black shirts since I can use the blacks of the shirt to compensate for hairs in the photos. Is there a way to print photo images on dark shirts other then black?

Ryonets process colors
Are related international coating inks and they do have a process black

I figured out your talking about the spot process inks. You just use the 700 series black for your black ink.

 

[Slee410]

I see, but in separation studios theres no black channel, how do I create a black channel?

 

[Slee410]

Ok I think I figured it out, theres a generate black option. Not the most accurate but I think I would need to play around with each of the channels.
