Printing with the Four-color Process
- Call us first to discuss the print job. If it is revealed that our workmanship or the materials we used are the cause for problem, we will issue you a written authorization for reprint.
- Ship the original product back. Please package the pieces carefully so they are not further damaged in transit, and send them back to us using UPS Ground or a similar service.
- Look for a revised proof. Before redoing your print job, we will send you a new proof. Please scrutinize it very carefully! Once we receive your approval of the proof we will redo your print job as quickly as possible.
- Receive new product. We will ship your reprinted product to you at our expense.
The four-color process divides images into four color values that are transferred to printing plates and sequentially printed on a printing press (also known as offset printing).
The four colors used and the four-color process are commonly referred to as CMYK, which stands for Cyan, Magenta, Yellow, and Black. The printing press recreates the original images using the four colors of inks at different values.
Computer monitors typically present colors in an RGB color model, which stands for Red, Green and Blue. While these colors might look good on your screen, they are not necessarily representative of what they will look like when printed. It is highly recommended that you create your Artwork using the CMYK color model.
Converting from RGB to CMYK
So, what if your Artwork was created in RGB? It�s OK. We can tell you how to convert it, or convert it for you.
Of course, it�s always better to develop with CMYK in the first place. Following are some helpful instructions for assuring that you are using the CMYK color model in development within some popular design and development programs.
Microsoft Publisher 2000
Unfortunately, Microsoft Publisher defaults to RGB. To convert or start a document in CMYK, use the following menu options: Tools/Commercial Printing Tools/Color Printing and select Process colors (CMYK).
Please note that all images incorporated into a layout must be linked, not embedded, in order to maintain the CMYK color space within the image. You can accomplish this by using these menu options: 1) Tools/Commercial Printing Tools/Graphics Manager; 2) highlight the embedded image; 3) click Link; 4) click Browse to locate the original file; and 5) link to it.
Important Note: When uploading files to our prepress department, please send us both the images and the layout file.
