how can i get spot colour tints working with pantone?
I’m using Shiraz RIP v7.2 with spot colour replacement.
The spot colours work fine apart from when using tints (eg. 50% Pantone 485 C) it prints at 100%, only way round is to convert the colour in my file to process.
I know this isn’t an error in the rip just something it’s not programmed to do, does anyone know if the newer version of Shiraz has the option to print spot tints? Or are there any other quick fixes i could try?

I thought 6.4 was the latest version? they must have released another one
I use PDF’s from Corel… when I Publish to PDF "Preserve halftone screen information" needs a tick in it and preserve document overprints also a tick.
One other thing, search for the pantone matching file, in there you will find all the Pantone Names, but they are called Spotcol .. i am searching my drive, I cant find it, i know its in Shiraz folder somewhere.

the reason it replaces is because the rip is looking at the name of the colour rather than the cmyk makeup. the rip cant (or at least couldnt) recognise when you select a percentage of a spot colour.
so if you have a 30% tint of spot 123, this is just recognised as spot123 at full colour. i thought they had sorted this though. its not a bug, just a limitation.

by the way Dave, \shiraz\profile\spot ssc files open with notepad.

yes, its the halftone information removed from PDF’s while being published is what it is.
I spoke to AIT, the RIP software is 6.4 is the latest not 7.2Thanks for the file ref

In the Design, Colour tab on version 6.4 the spot colour profile is set at none (or whatever you have it set at) – there’s a check box underneath it. If you remove the tick from the check box when you print tints – it will print tints & not 100%.
You just have to remember to do it!!

while this will enable you to print tints it will also disable the spot colour replacement.
therefore your spot colour may not look as you desire. you’ll have to go back to the old route of using exact cmyk values to make both you solid colour and tints.
problem is printing spot tints whilst still matching to solid spot colours.
