Can't hit my color

use kapco yellow?

sorry, I had to redo two 48" logos for a sprinter van in cut vinyl, because I couldn't hit a bright enough yellow on my Mimaki either... but I hope you & I both learn how to do it.

 

What is a close Pantone match to that color (just so I know what we're dealing with). Also, rather than doing this in PS, can you set the yellow up in a vector file? Try setting up some swatches with a CMYK yellow mix of 0/0/100/0 and slowly adding a percent or two of magenta.

I get much more vibrant, clean yellows when printing from a CMYK vector file than a raster image which tends to "muddy" yellows (especially those containing a bit or magenta).

 

Are you using any colour management software and making your own profiles? From time to time I here different people saying they can't hit certain colours on there printers, the olnly colour I had problems with was a green that almost looked like day-glow green, but after making a few adjustments it was passable. I don't think you get much out of them canned profiles.

 

I really think you'd get a more vibrant yellow if you skipped the rasterizing step. Try printing from a vector swatch and see what happens.

 

Depends. What are your rendering intents?

The best way to go probably is vector but set your rendering intent to either 'No Color Correction', 'Spot' or, second choice, 'Saturation". Or, best of all, turn off your color correction altogether.

If you're absolutely stuck with a bitmap use a rendering intent of 'Perceptual'.

You Are Using Onyx Where You Able To Get The Right Profile I Know Kapco Doesn't Have Much Out There

 

Nature of the beast, limited color gamut with solvent inks.

 

We have the same problem with Mutoh Valuejet and mamaki solvent, try to match Valero yellow, which is similar to Arlon Calplus yellow, no can't do.

 

Hrm, bummer. It for sure looks like something we can get on the roland with eco-solvent. Close to signal yellow vinyl (which is oracal I think?). Anyway, I assume those 40 little color boxes already had this, but I can see it's yellow with a smidge of magenta. I'd probably make 10 boxes and have each one add 2% more magenta to 100% yellow, one of those should be it. If it isn't... I guess your printer is weaksauce

 

Have you tried a color replacement in Onyx? You can bypass the profile and monkey with pure hues. Vector colors work best. If still no dice your yellow is probably outside of the ink gamut.
Good luck

 

... actually, solvent inks have slightly WIDER color gamut then traditional offset prints. So, U might get better results if You prepare for print in RGB mode, and then try using color profiles to get the most out of it (so - machine will transform Your colors to a closer match).

 

Try turning off color correction, then specifying the 0-0-100-0 and going from there, with spot color. We have done this with success a couple of times.

If the color correction is on it is harder to fool the rip, as it still uses all colors for 100%Y.

 

You may have better luck with a mix of 17% magenta with 62% yellow. Let me know if this if this works and I will tell you my trick.

You could also print all of your other colors on white vinyl, contour cut, apply tape, and transfer onto your Kapco yellow vinyl, and them laminate.
