: Should I work in CMYK when printing shirts using Direct-to-Garment (DTG)? I've just read What kind of black should I use when designing for CMYK print? and I'd like to ask if these considerations

@Vandalay110

The idea of suing CMYK for print has to do with how 4 color offset printing works. It does not necessarily apply to all other kind of printing, there is nothing that states you could not use other color primaries in your print. Old school comics used this method so if they wanted red they printed red.

The benefit of printing with the primaries your printer uses is total control. Leaving the result to the color system is more error prone and it does not allow you to use colors that over exceed your RGB spectrum. However like Rafael points out sometimes you need to let the printer do the work, because you can not do a 7 color separation, and hope for the best.

Direct to garment is a digital print. If you do not have the specific CMYK profiles it is recomended that you send the file in RGB with R0G0B0 values as black.

A lot of people think that a CMYK output is a must when sending to print. It is not. Sometimes you need to avoid it.

It is a must when sending it to a CMYK separation, like offset print or color selection silk print.

But on a digital output (unless you have total control on the rip) you need the rip decide the separation of colors. Some printers can use 6 inks, some use diferent color profiles, some will have some built in tweeks to make your print "pop", etc.


If you have the same design going for print, web, and fabric, do you have separate source files having the specific colour profiles?


Interesting one. Yes.

You should understand what a color profile is.

It is a series of "matrixes" to adjust colors depending on the conditions, to be printed or viewed. Ink types, brands and surface to be printed.

Coated paper, office paper, newspaper, cotton fabric, sinthetic fabric, silk print, offset print, sublimation, inkjet print. Japaneese inks, german inks, north american inks. Transparent inks, opaque inks. 6 color separations... a big etc.

So the answer is yes at some extent.

At least you need a sRGB rgb profile for web, or drop the profile completly. The CMYK profile is only to see the colors somehow similar to a print, but on an RGB file is not stored.

On a digital oputput you could use either Adobe 1998, ProPhoto RGB or sRGB.

On a real CMYK output you need at least a standard profile depending on your region and basic paper type. (Swop, Gracol, Fogra, Japan Standard)
