4-14 Computerized Controls

If your graphic contains colors other than the ones in the Printer Driver, the driver will attempt to

match (map) each color to a color in the driver that it most closely resembles. The driver will

then use the mapped color’s power setting, and apply a halftone pattern to represent the

graphic color’s shade. For example, if using a color such as pink to fill a rectangle, the Printer

Driver looks at the CMYK value of the pink color and will map the pink color to the color in the

Printer Driver that it most closely resembles. You might expect that the Printer Driver will use

the power setting assigned to the color red but instead the Printer Driver may choose the

magenta setting and halftone the rectangle as a representation of the pink color’s lighter shade.

Therefore, to prevent the incorrect assignment of laser power, be sure to use the correct colors.

If you are using graphics with colors other than the eight listed, such a Clipart image you

imported from the CorelDRAW Clipart disks, try using the Clipart Mode feature in the Printer

Driver.

Outlines and Fills

The driver distinguishes between raster mode (engraving) and vector mode (cutting) by the type

of graphic artwork being used. Basically, all graphics other than outlines of very thin line widths

will be interpreted as engraved images and the raster mode will be used for output. If laser

cutting is desired, set the line thickness of the lines that are drawn in the graphics software to

.00005 inches (.01 mm) or the smallest possible line thickness that is available. The printer

driver will interpret these objects as vectors and will cut them out providing that your software

has the capability of vector output. Basically, all software programs have the ability to provide

raster output. However, not all programs have the ability to provide vector output even if you set

the line width to the smallest thickness possible. Check with Software Anomalies section in the

back of this manual for software that can vector output. The use of color fills or bitmaps will

cause the laser system to engrave. The combination of engraving and cutting is available in

most graphics software. We suggest that when combining engraving and cutting objects, use

different colors for the fills and outlines since engraving requires different power settings than

cutting objects. One thing to keep in mind when creating cutting objects is that if the outline

thickness is set too thick, the driver might interpret the outline as a filled object and will engrave

the outline instead of cutting. This might be desirable if engraving thick outlines is necessary.

The outline thickness at which the driver will interpret cut lines as filled objects is dependent on

the software used. Usually, any line thickness .008 inches (.2 mm) or greater will engrave. The

only way to determine the cross over point for line thickness is to experiment with different line

widths. Software programs that do not have outline capabilities definitely will not have the ability

to cut.
