24bit colour export format for versaworks

Hi everyone,

I am not sure if this question has been asked but I need to know the answer.

I have a roland sp300v and currently export my coreldraw files by eps (only 8bit colour), now this might be a silly question, but if I use this format on a 24bit colour image wont this change the colour of the image as the colour range as reduced?

A further question I have to ask, is I have tried a tiff (24bit) and a pdf (24bit), but versaworks does not recognise the cut lines, what have I done wrong and what's the best format to export a 24bit rgb file? Does anyone have any suggestions and what formats do the forum members use?

I would appreciate any input my fellow members may have and would like to thank you all in advance for your help.

Kind Regards.

the only true 16 bit rip program I know of is Wasatch...that being said ,....I have printed with same image with Versaworks and the difference to gradients is really minimal. (just make sure your "steps" in the gradient fill are set high). Versaworks is fine....I don't think the extra cash $1600cdn. is worth buying wasatch...as it is NOT a true rip and cut program like versaworks, as they would have you beleive. (the cut file is a whole separate file to send)....pain in the #%^^$

You have the option to select a jpeg or a tiff as Lossless (no compression). If you are experiencing radical color differences then I would Immediately get away from Corel and use Illustrator and Photoshop...In the past most color issues I have had always involved Corel...rarely Adobe programs. (Although i find Corel and signlab far easier to design in, I have to admit that they are not the best for color). try your contour cut and jpeg in illustrator and turn it inta a pdf file. make sure your PDF settings are set to NOT downsample bitmaps and that you select "include all color profiles"....(you always want to make sure your photos print with a SRGB profile assigned) I often find that a clienst photos have no profile assigned....and the differenc ir remarkabl (try it)... hehe

I would have you use Adobe RGB1988 instead of SRGB - SRGB is a smaller color space and you will lose color. Usually when people have issues with color on raster images out of Corel they are exporting them as a CMYK color and have the space clipped. You need to maintain it as an Adobe RGB 1988 all the way through the process and let Versaworks convert them for the printer.

you may have had the cutline converted to a process color unless you had it as a separate vector object. As a tiff, it would not be a spot color anymore and Versaworks will not find it. In a pdf you can have both raster and vector images so it should work if exported properly. Versaworks will work with 24 bit color.
