QTR-Quadtone RIP

i'm new to this group. hello!

i have a epson r1900. i'm printing on transfer paper for t-shirt transfers.  i got like many people a green blue tone to my photo prints.
after trying and trying for hours i get some good output on grey's not to much Metamerism (which causes the greenish glow i think)

i'm desparate to find a way to make the printer prints grey with the blacks only.  can this be done with quadtone rip?  i dont want a composite of colours to create grey, i want only the blacks to produce it.
is it possible? any suggestions?

Joris,

Welcome to this group.

What you ask is very well possible. However, I checked my version of QTR and it does not contain curves for the 1900 yet. The "curves" describe how ink channels are used exactly. In your case you could use a "black only" curves, actually the easiest curve to make. Perhaps the newest version of QTR has 1900 curves. You may also check the "files" section of this group. If that doesn't help you'll have to make your own curve. You can check out Tom Moore's manual for that.

Good luck,

Joost

As an afterthought, you'll need to make your own curve anyhow as you're printing quite non-standard (at least for us) material. But there will be curves that you could use as a starting point.

thanks Joost!  i'm going to dive into this.  first i will start reading about what is a curve and how i can make one...


thanks.

You said that you want to print black only because you are not getting neutral greys using the colour inks. This is not at all unusual when you are using such an indirect printing process. Have you tried a custom profile for your (colour) process? I know from experience that this has solved the problem for some people using transfer printing methods.

I'm not suggesting that QTR is not great for B&W - I have used it for the past four years with my own curves - but given that QTR does not directly support the R1900, a good colour profile may be an easier route for you.
