# 3472- Assigning Pantone® Matching System Colors to Bitmaps

Raster images or bitmaps are generally CMYK or RGB.  As a result PMS (PANTONE®
MATCHING SYSTEM) colors are unavailable when printing separations. There are two ways to
assign PMS colors to a raster image using CorelDRAW™ 8.

Converting an Image To Duotone

To convert a bitmap image to a duotone in CorelDRAW™ 8.0, first import the bitmap (.CPT,
.BMP, .TIF, .JPG, or .GIF).  Select the bitmap with the pick tool.  Click on the Bitmap menu and
select Convert to, Grayscale. Click on Bitmap, Convert to, Duotone.  To change the color to a
Pantone color, double click on the Pantone color to obtain the "Select Color" dialogue menu.  Once
the color is selected, click OK and then click OK again to exit the "Duotone" dialogue box. 

The image can also be converted to a Monotone, Duotone, Tritone or Quadtone using the duotone
dialogue box.  Any combined PMS colors create the appearance of another color space.

Using 1-bit Monochrome Images

To convert an image into a 1-bit monochrome bitmap, first import the bitmap into CorelDRAW. 
Click on the Bitmap menu, Convert to, Black and White (1-bit).  Select the desired Conversion
Method, and then click OK.  Now that the image is a 1-bit bitmap, select the bitmap with the pick
tool. Using the outline tool, select the desired PMS color.  Assigning the outline color changes the
black pixels in the image and assigning a fill color changes the white or transparent pixels in the
image.

To verify that the bitmap is separating on a Pantone plate, click on File, Print Preview.  Click the
Options button, the Separations tab, and enable Print Separations, click OK.  Each of the separations
should now be displayed.

Creating a Duotone Image In PHOTO-PAINT™ 8

Open the bitmap image in PHOTO-PAINT™ 8.  Click on Image, Convert To, Grayscale (8-bit). 
Click on Image, Convert To, Duotone (8-bit).  Select the Type: Monotone, Duotone, Tritone, or
Quadtone.  Double-click on the Pantone color name to open the Select Color dialog. Select the
desired Pantone Matching System color and click OK.  Click OK again to complete the conversion. 
Now save the file to the EPS file format.  Click on File, Save As, enter a filename, select
Encapsulated PostScript® (EPS) from the Save as Type list and click the Save button.

The file is now ready to be imported into CorelDRAW 8 or an other application that supports the
EPS file format.   Use the Encapsulated PostScript (EPS) filter in CorelDRAW 8 to import the file.
