Deneba Canvas 8.0 for Macintosh

PLEASE NOTE: When creating graphics in illustration programs such as Deneba Canvas 8.0 for outputting to an imagesetter or platesetter, it is extremely important that the person creating the graphic have a thorough understanding of imaging in a prepress environment. There is an abundance of complex problems that can occur at output if paths are set up improperly, colors are indicated incorrectly, or other elements such as traps are constructed improperly. The more complicated the graphic becomes, the greater the possibility of problems at output, and therefore the greater need for expertise and experience in creating the files.

This instruction set covers the following important procedures:

Preparing Graphic for Export and Exporting CMYK, Grayscale or Line Art

Preparing Graphic for Export

1. Place any graphics. Before placing images, they 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 Mode can be Black & White (bitmap mode), Grayscale or CMYK. CMYK 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 before importing so that masking, scaling or rotating is not necessary while in Canvas.

Canvas Tools: An image can be adjusted within Canvas. Choose Image > Mode to view and correct the color space. Choose Image > Area > Resolution to alter the resolution.

Go to the Place... menu (File->Place...) and navigate to the TIFF or EPS file that you wish to place.

If you select an EPSF graphic to place, you will be prompted with another dialog box for EPSF Import Options. Select Create Canvas Object as shown:

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 four-color graphics are in CMYK format. RGB files, which will not output correctly, may not be detected until output. If necessary, use Canvas' tools to convert RGB to to the proper color mode.

3. Convert all text to paths. With the text selected, select Convert To Paths (Object->Paths->Convert To Paths). This eliminates the requirement of sending CPC fonts. There isn't a quality loss when converting text to paths.

Exporting CMYK, Grayscale or Line Art

1. Save the graphic. Bring up the Save As dialog box (File->Save As...) and select the File Format EPSF and set all other settings as shown:

After you press Save, a dialog box will be presented that warns about saving files in formats other than Canvas, press Save again.

2. Setup the EPSF Export Options.

  • For EPSF Type select EPS
  • For Preview: select Macintosh PICT
  • For Image Compression: select ASCII
  • For Color Mode: select CMYK, Grayscale or Black & White
  • For Transparency Rendering: select Smallest Area
  • For Rendering Resolution: select 600
  • Keep the rest as is.
