[ECI-EN] Re: RGB to CMYK for silk-screen printing

Try using one of the GRACoL Coated family of ICC profiles. You'll be retaining a bit more "RGB colors", this way. But you're essentially at the mercy of silk-screen printing. If your artwork allows and your printer is able to use inks other than process colors, you will get more of your work by manually converting to Spot colors. Instead of printing with CMYK inks, you'd be printing with 4 or more, say, PANTONE colors, including those fluorescent colors you mentioned. This approach is likely to cost more, in terms of printing. It's a more complex process but, depending on your artwork, very well worth it. / Roger Breton -----Original Message----- From: contact(a)blandinesoulage.com <contact(a)blandinesoulage.com> Sent: Wednesday, January 10, 2024 6:52 AM To: eci-en(a)lists.callassoftware.com Subject: [ECI-EN] RGB to CMYK for silk-screen printing Hello, I'm a French visual artist working with silk-screen printing seeking for advice. When I convert my RGB files to CMYK, I lose a lot of color data and radiance. I use the Web coated swop 2006 profile to convert from RGB to CMYK. Which colorimetric profile should I use to reduce data loss during conversion? What about converting with a “multichannel” profile? Apparently it's also possible to use "Edit/Convert to profile/Custom CMYK", but I don't know what the values to be assigned correspond to. I work in 2, 3 or 4 color process using layer separation in Photoshop. I then recreate my CMYK manually by making my own inks. Sometimes modifying them. For example, I use fluorescent colors or a dark blue instead of a cyan.... Once the conversion is made, the CMYK profile that i use should thus be wide enough so that my simulations are as close as possible to the rendering I will get with my inks.
