can anyone help print ultramarine on jv3 please?

[Peter Normington]

Richard,
what do you mean, keeps turning purple?
does it print blue then change, or just print purple everytime?
What software/rip are you using?
Are you sure the original colour is ultramarine, or is that just how it appears on your screen.
are you using any colour profiles? and what material are you using?

I may not know the answer but the extra info may help
Peter

Thanks for getting back to me

The colour itself keeps printing purple.
Im using Shiraz with hexis v350 vinyl.

Usually when i design the artwork i assign the colour match in flexisgn, when i export it, its a pretty good match to the vinyl.

But someone has sent me the artwork this time so i cant take it into flexisign withou the other colours changing.

Thanks again Peter

[Peter Normington]

Sorry cant help with flexi,
But is it possible to open the file in corel, or illustrator, determine the colour value, and assign it in flexi, or add to your palette?

I may be completely wrong, so I will leave it to the more competent than I

We have a similar problem with our Cadet plus.
One of our regular customers uses pantone 286 blue as one of their corporate colours. If we set a 286 blue background to their signs in Flexisign, and export it as an EPS file to the Troop Rip, the printer changes the colour completely to a purply blue. I’ve tried adjusting the 286 colour in Flexi, but can’t get anywhere near to the correct colour.Ive also tried working through the pantone pallette printing out all the blues, but can’t get anywhere near 286 blue – or any other "vibrant" blue. Because of this problem we tend to do this customers work in vinyl, which can be very time consuming.

Hi all

Can you not get an PANTONE to CMYK chart and match the vinyl to the PANTONE reference and just adjust with the CMYK values!. It may need a little tweaking but you should be able to get a reasonable result.

Kind regards

shiraz has a colour matching system that recognises colour names. so if the name has a pantone reference it gets replaced during the rip stage.

you should have an option in the design screen to disable this.

also check your rendering intents in the rip (whichever rip).

if you have 3 pantone colours in the file for example and you have the rendering intent set to perceptual, then the rip will look at the colours it cant hit and compress them to fit within the printers cmyk profile colour space.

however it Will adjust the other colours that it could already accurately print to make them suit the colour that was out of gamut. now it might have been that 2 of the 3 ptone colours were achievable but the 3rd one is the one that causes all the others to be changed to suit the out of gamut colour.

colorimetric rendering for these types of jobs will preserve similar cmyk values to when the file was created. it will also move any out of gamut colours into a printable range but it will not adjust the already achievable colours in the file. therefore more suited for corporate or ptone colour matching.

hard to explain, hope it makes sense. i may write this again when im not so tired… also pictures help.

thanks for that mark, i did wonder how they worked.
Just a note that Shiraz doesn’t convert all colours to Pantones as they have to be renamed in the colour file as they are called "SPOTCOL" instead of "PANTONE", for licensing reasons.

Purple is in indication of profile being a bit off, although you will notice that a few other colours are hard to print. Should be quite noticable.

We use Avery 2000 with Avery 2000 profile, great results.

hi dave, if the file to be printed has a reference to pantone, then shiraz knows to replace this with spotcolour as you said. the only time you used to have to change the spotcolour table was to replace C with CV to determine which ptone tables you were using in the design package.

at least thats how it used to be about 3 years ago when i worked there, i think the latest (6.4? ) doesnt need that any more.. still waiting for my new license so i can test it.
