Bonjour Blandine,
j'avais quelques questions :
si je comprends bien, vous imprimez 4 typons (ou plus) pour vos tirages
sérigraphiques
Chaque typon sera pour une couleur spécifique par exemple : bleu foncé au
lieu d'un cyan, Magenta, Noir, Jaune
Pour les couleurs fluo, vous rajoutez un film supplémentaire
Quelle imprimante utilisez-vous pour imprimer vos films ?
Quel type d'encre ?
Quel tramage ?
merci de détailler pour mieux vous renseigner
Cordialement
*Philippe DAUBRESSE*

Dear Roger,
Thank you very much for your precious response.
Do you actually speak French?
I would be very interested in learning to convert from RVB to Spot colors
since I actually print my artwork manually with silkscreen printing and
making my own ink.
Thank you for your help and have a lovely day,
Blandine

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.

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.
Thank you for very much for your help
