Preparing Digital Artwork
for Cadmus Professional Communications with

CorelDRAW 6.0 for Power Macintosh


PLEASE NOTE: When creating graphics in illustration programs such as CorelDRAW with the intention of outputting to an imagesetter or platesetter, it is extremely important that the person creating the illustration have a thorough understanding of the details of imaging in a prepress environment. There are an abundance of complex problems that can occur at output if paths are set up improperly, colors are indicated incorrectly, or other elements are constructed improperly. Trapping issues can also present problems if not addressed. The more complicated your illustration becomes, the greater the probability of problems at output, and therefore the need for more expertise and experience in creating the files.


This instruction set covers the following important procedures:

Preparing Graphic for Export

Exporting Line Art

Exporting Grayscale

Exporting CMYK


Preparing Graphic for Export

1. Import any external graphics needed. Before placing images in CorelDRAW, the images should be checked for the following:

  • All placed art should be in TIFF or EPS format.
  • The resolution should be at least 300 dpi
  • The color mode of the TIFF/EPS should be either Monochrome (bitmap mode), Grayscale or CMYK. The CMYK mode is used for color figures and Grayscale/Monochrome for black & white.
  • Please note: Some journals now require that color be submitted in RGB color mode. To learn more about the RGB workflow click here.
  • Crop and size images properly before importing so that masking, scaling or rotating is not necessary while in CorelDRAW.
  • Make absolutely sure that you do not import any RGB graphics, as they will not print correctly. They are very difficult to recognize before output.

Go to the Import... menu (File->Import...) and navigate to the TIFF or EPS file that you wish to import. Use the following options for placing TIFF or EPS files.

2. Do all editing and assembly.

  • Assemble any panels so that each figure consists of only one file.
  • Create the figure at 100% of print size so that no scaling is necessary.
  • Make sure that any and all imported graphics are in proper color format. RGB files, which will not output correctly, may not be detected until output.

3. Resize the Page. On the CorelDRAW menu bar, go to (Layout->Document Layout). Resize the page so that there is no unnecessary white space is bordering the figure (shown below).

 

Page Setup


Exporting Line Art

Note: When exporting figures to be printed as line art, be sure all objects in your CorelDRAW file are black or white only.

2. Choosing EPS Export Options. After pressing Export, you will see the EPS Export dialog.

Exporting Grayscale

1. Export the graphic. Bring up the Export dialog box ( File-> Export ) and select the Format: TIFF Bitmap (TIF) as shown:

2. Choosing Export Options. After pressing Export, you will see the Bitmap Export dialog.

  • Under Color choose 256 Shades of Gray
  • Under Resolution choose 300 dpi identical values, as shown (if you are exporting a combination halftone, you can go up to 600 dpi for the resolution):

For TIFF Output Options choose "LZW" Compression as shown:


Exporting CMYK

Note: When exporting figures to be printed as CMYK, be sure that there isn't any RGB Objects in your CorelDRAW file.

1. Export the graphic. Bring up the Export dialog box ( File-> Export ) and select the Format: Encapsulated Postscript (EPS) as shown:

2. Choosing EPS Export Options. After pressing Export, you will see the EPS Export dialog.
