[Chris Wool]

First off, the answer I give is based on JV3 with a profiled Shiraz software using Corel’s PDF format for file transfer.

This may sound daft but what colour is Gray? there is so many ways to make gray… is it C: 0 m: 0 y: 0 k: 50 ? or grayscale within a bitmap? gray solid fill?

When a colour profiler sets up a machine, they are keen to see a gray bar print as it will tell them which way the material profile is leaning for fine tuning, they then will print a calibration chart and read it into the RIP to create a values that tells the RIP how to print that media. Are you using a profile provided by SignLab, is it marked for that material?

However, I have seen it happen with wrong temperatures or crap media.

[Nick Minall]

what inks are you using? if Uniform then Versaworks will not have the profiles you need, SL probably wont have the as well.

Hi Phil, I agree with Dave & Chris, sounds like a profile problem / material issue..

[Graeme Speirs]

i changed inks in my cadet.

I had some prints turning a pinkish colour. Go into the print properties (i have troop) and nudge the magenta down about 10-15% and play about until your happy. Was actually a great way to learn more about my machine. Drove me mental on some supposed black and white canvas’s I was printing.

using activasol inks, have played with some settings, can get the car to print black then the colour of the text changes to a washed out brown colour, we are looking at getting troop rip s/l is just far to over complicated for my limited knowledge to take in..

[Chris Wool]

if its a cadet you should already be using troop what are you using and what profile.
also how are you sending the file to the rip and from what software

yeah we found this out after the "sales" team said we didn’t need it, we run s/l 7 and usually rip direct, using a generic profile for std prints its ch of this been fine ish..like i say i don’t pretend to understand much of this print process just enough to get by..your help is greatly appreciated..phil

I don’t run a printer so just throwing this in the pot.

Is there not an option to print black as black in the RIP rather than it being made from a 4 colour split.

[Phil Veitch]

if there is i can’t seem to find it, s/l print n cut is complicated enough with trawling through 2000 option buttons..

Gonna tell the customer he has to have a red car n never print black again lol.. (:)

Hello Phil
I can identify with your problem.
We had the same issue a year ago.
We were using Citrosol inks (with Versaworks) and had no previous trouble with them over two years but they changed the formula of the yellow (and I don’t know what else). The results were terrible with blues printing purple and greys printing brown.
The local agent for Citrosol didn’t want to know about it so we changed to Techinks with their profiles.
The result was accurate colour matching 99% of the time and also heads lasting much longer.
Profiles are a very exacting science and other than minor adjustments we don’t touch them.
Hope you get a resolution.

I dont think this is your problem but to find the "preserve black" options, in the rip you need to go to printers/manage print modes/
then choose the material you are using, then right click and make a copy, this is important as you will change settings and need to keep the original.
choose the copy and right click to edit, choose the ICC profile section, tick the box to override, then on the right of the input profiles click the scroll arrow and you will see the options regarding rendering intent and preserving black.
make your choices and then save, its handy to rename the profile as something to give a clue how you changed it eg hexis 720 x720 black preserved.

now you need to create a new queue using this print mode and do a test print.Peter

I use SL8 so not sure if the options to get to the profiles were the same in 7
but I think they were similar.

when u posted a third party ink, i knew then your colours wont be bang on.

tbh… when a printer is sold, when it is installed and tested, the operator should start profiling banner and standard white vinyl there and then.
The big printers mention this to us (like durst, HP but not the smaller ones etc)

[Phil Veitch]

thanks for your help guys, will just have to get in and have a play, have sort of got it so the customer is happy with it, turned the magenta down not perfect but its been signed off..

Just ordered troop rip, so will be back with more questions …lol

Thanks Guys
