2-2 Creating Data for Printing
Basic Ideas of Creating Data
You will use two layers (CMYK and white) to print a single image, so keep the following things in mind:
G Make the two layers precisely form the image you expect when you create data for each layer.
You can use any application software as far as it can save files in a format that can be loaded into Roland VersaWorks.
Commonly, it is recommended that you use Adobe Illustrator, because you can create multiple drawing layers in a
single file.
G Save each of the layers as a PS file before you actually print the image.
You will print each of the layers separately, so it is necessary to create two separate PS files.
Spelling out the obvious about white...
G Usually, you use white paper for printing an image. When the image has white part, it means that the part has no
color (C=0%, M=0%, Y=0%, K=0% in CMYK). When printed on the paper, of course, no color of ink is on it where
the image is white. If you use transparent media for printing the image, this "white" part of the image becomes
transparent, because no ink is on the media. If you want to have white part printed white on transparent media,
you simply need to use white ink. A PS file that contains white layer of the image, or white data, is necessary for
printing with white ink.
G When you create data for white layer of the image on your computer, you have to use solid black (K=100%) for
drawing objects in it. Solid black is interpreted as solid white when the data is printed.
Basic Flow
Roughly design or draw your image which contains white part as an element of the image.
Draw the image you have designed on your computer using Adobe Illustrator or other graphic application software.
G If you use Adobe Illustrator, draw the CMYK color part of the image in one layer, and the white part of the
image in another layer.
G If you use other application software, it is necessary to think about how to draw each of the layers. You may
be able to draw both layers in a single file just as you can do using Adobe Illustrator, or you may have to
create a file for each layer. It depends on the application software you use.
Save the file(s) that contains the image you have drawn as PS files.
G If you use Adobe Illustrator, save each of the layers (CMYK layer and white layer) in the file you draw as a PS
file. As a result, you will have two separate PS files - one for the CMYK layer of the image, and the other for the
white layer of the image.
G The above rule also applies when you use other application software. Make sure that you create one PS file
per each of the layers of the image.
Operational Procedures
In this example you will use Adobe Illustrator CS to create data for printing.
Important!
G For details about how to use Adobe Illustrator such as drawing objects or handling layers, see the manual or
online help that come with it.
G The following operations apply only Adobe Illustrator CS. If you use one of the other versions of Adobe
Illustrator, operations may be somewhat different from those explained here.
