Where would that info be? im using versaworks rip, i selected high quality with correct metamark media and colouir profile, next to the word resolution, 1440×720 is greyed out.

The file itself is from corel draw 12, with a contour cut line around the outside, i exported it as an eps

Any views?

Hi
try making your grey a tint of black as in C= 0% M= 0% Y= 0%
Black= 5%-95%

at that res it should be a very smooth colour to the eye, but not under a magnifying glass. do you see specks of different colours.

[Jonathan McGovern]

no colour, just grey and white, roland did mention that it can lay colour around the grey, but all i can see, even from a distance is speckled grey/white.

I printed a job last week (Cadet / Vesacamm 540) that was predominantly solid greys – from very light to very dark. Without fail, it’s a mish-mash of speckled dots in every conceivable colour to get the dither & shade right. Up close under close scrutiny it’s quite noticeable…look from a couple of feet away & it’s pretty much perfect.

Unless you can do it as a monochrome dither using only black & dot size / spacing to achieve the tints – that’s probably the way it’s going to be as it’s not really a fault.

the grey i am printing is cmyk 30% black

[Jonathan McGovern]

how can i do that David, this is all new to me!!!!

[David Rogers]

quote Jonathan McGovern:

the grey i am printing is cmyk 30% black

In your RIP software – is there an option to do it in monochrome and not CMYK…then it can ONLY use black to achieve the tint. But it will be a tint of black…and probably even MORE speckled (although all black dots).

[Kevin Flowers]

Hi
in versaworks you can designate a certain colour as in
CMYK % to only print CMYK %. So if you specify K 30% then it will print K30 %. Not got Versaworks in front of me so can’t give you the full Sp

often wanted to look at versaworks just went to down load it and its asking foe a chassis no.

i run colour rip and i know VW will not drive a non V roland just wanted to see

any problem anybody pm me a chassis no please

chris

[Kevin Flowers]

Chris
Chassis No. won’t help you, it searches for attached printers & won’t start if it doesn’t find one. It basically talks to the printer & asks for set up & ink type then loads the appropriate profiles etc.

i though the new roland rip software has a spot color matching system, or is that an optional software ???

Chris, Versaworks will only work if it finds a printer mate, but you only have to do it once, it will then work ok on its own.

I find the spot colour matching the best way to go using corel i give the colour a spot colour from the roland swatch . When I got the printer I ran the colour charts from the rip on to the different media’s

[Chris Wool]

thanks for info .

jon have you tried printing what you asked for in the quote forum on to a grey or flat silver vinyl.

i use image perfect 5700 for this sort of thing, the colours are altered by the non white background, but a tweek on the colour curves in the rip, can bring them back sometimes.

remember to save the altered profile to different name thou

chris

ps saves on ink as well
