PLEASE NOTE: When creating graphics in illustration programs such as ChemDraw Pro 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.

Saving Black & White Figures

As Monochrome TIFF

Note: When exporting figures to be printed as pure black & white (line art) do not use objects with gray shading. ChemDraw has problems rendering shades of gray as pure black and white (Monochrome TIFF format).

1. Create the graphic. See Guidelines for Sizing.

2. Choose Save As. After creating the graphic, choose Save As (File > Save As) from the ChemDraw Pro file menu. After the Save As dialog box appears (shown below), select TIFF as the file format. 

3. Next press the Options button to choose the appropriate TIFF options.

• Resolution: choose 1200 dpi 
• Colors: choose Monochrome 
• Compression: choose PackBits 
• Press OK 

As EPS (the EPS format will create smaller files than Mono TIFF)

Note: When exporting figures in EPS format only use CPC supported Type 1 printer fonts.

1. Create the graphic. See Guidelines for Sizing and Font Usage.

2. Choose Save As. After creating the graphic, choose Save As (File > Save As) from the ChemDraw Pro file menu. After the Save As dialog box appears (shown below), select Encapsulated PostScript (Mac) as the file format. Press Save to save the file.
