BRIGHT COLOURS

[David Rogers]

For what? Just on screen or for printing?

Doesn’t matter which program you use to try to mix up the colours to print digitally, flourescent colours cannot be made out of CMYK, CcMmYK, CMYKOV or anything similar.

In screen printing, litho, flexo etc. flourescent inks are applied as spot colours.

Hope that helps.

hi, thanks for that rob.

it is for both on screen and printing with our versacamm, the problem i seem to be struggling with is that the colours just look drab, orange for example is more of a brown orange than ORANGE, if that makes sense?

cheers

You’ll find some colours are really hard if not impossible to get.

I find blues hard to match and looking at my printed chart so is orange and purple.

Have you got your monitor calibrated as this does help.

Hello Stephen,

Don’t know if you got your brightness problem sorted but I had a similar problem with print output not matching screen colours.
A workaround is to download a Pantone colour chart (available from uniformdigital.com) and print it on the media you want to use.
Keep this as a colour reference when choosing job colours. Enter the appropriate PMS number from this printout into Coreldraw. You can then be pretty sure of visually matching the required colour.

Cheers

Yes that’s what I’ve done, the engineer who installed my printer insisted on printing it so that I had the chart available.

If you look at the printed colours though and then match them to the PMS chips you’ll notice some of the colours match very well while others don’t.

Yes Steve,

It can be a bit of a balancing act at times. What the printer produces dosen’t match the "official" PMS colours but at least you know before output if there is likely to be an issue and take remedial steps
It’s good to show a client and get him or her to choose their preferred colour.

Hi

There’s another way but it takes a bit of time to get use to it if you’re not use to making your own colours.

It requires understanding how colours blend to make another. I’ve been painting in photorealistic work & colours for years and know the basic well.

In theory, one can mix any colour from the three primaries and white and black (but truth is pigment limits and mixing lower vibrancy). When it comes to cleaning up colours, or making them brighter, it is a matter of understand the core hue, and removing the rouges.

i.e

a purple has either a blue base or a red base depending on which side is stronger. what cmyk can do is add touches of rogue colour. i.e. a little yellow or black.

what you can do is alter the colour profile directly. click the colour you want to alter, know which of the bases are required and lower the complementary or rogue colour and if black is added lower that.

This may be difficult, but if you’ve got the time, give it a trailing. Goggle colour mixing and hues etc and see what information is out there to help you.

Hi Stephen,

I don’t know what program you’re using to print with (most likely Versaworks) but in ColorChoice you can change Bitmap Rendering Intent and Vector Rendering Intent.
What I have found is that I get much brighter colours using "Saturation" for Bitmap and "Spot Color" for Vector, if you haven’t already it might be worth giving a go.

Regards, Paul.
