I just ran it through RAL C1 software by DTP Studio as I been doing a bit of work on RAL just lately.

It is a little different to SignEmploy, where did you get those values from?

With Gloss
L: a*: b*: 81.42 -12.57 13.50
H: L: C: 132.96 81.42 18.45

Coated paper
C: M: Y: K:
35 0 40 0

Uncoated paper
C: M: Y: K:
30 0 30 0

without Gloss
L: a*: b*: 80.42 -12.88 13.51
H: L: C: 133.63 80.42 18.67

Coated Paper (%)
C: M: Y: K:
35 0 40 0

Uncoated Paper (%)
C: M: Y: K:
30 0 30 0

Again, I always say this …. i have in past given values that are wrong, someone then screws up a large print… if in doubt get yourself a RAL chart, it is mainly used in European paint systems including the UK.

The CMYK’s are actually ‘simulated’, the LAB values is what you should be entering as a spot colour replacement in the RIP and then using a named colour to print with. Then this is down to colour profiling and as with Pantone, RAL is just as hard to print.

Mike,

From experience, Green and Orange shades are almost impossible to match with any certainty.

I usually ignore the RAL colour guide, and just compare the colour to a cmyk pantone book.

If you have a mactac sample, it will be easier, but end of the day, its going to be difficult to get a close match.

I always tell my client that the process of digital print is vastly different to screen or offset, so comparisons will always be off, unless they want to pay my time to tweak it as best I can. Most will accept that close enough is near enough.

I’ve got a RAL pdf chart if you want one. I’ll email it over to you anyway.

Cheers
Shane

Welcome Kym. Just noticed its your first post.

Post something in the hello section, and tell us more about yourself.

A photo would be nice too 😉

thanks everybody it’s only for bumper stickers for a local cafe. it’s just me and the wife being a little anal I guess. It probably sounds really corny but we just want to be the best that we can be.

what are the lab numbers?? 😳 😳 😳

quote Michael Potter:

don’t ever be embarrassed or apologize about that Mike.

so much ‘near enough is good enough’ out there, its nice to find someone that is prepared to learn, at whatever age. Asking questions is the best way to do it too.
