Power

The Power table graphically represents the shoulder characteristics of the predefined rubber
stamp shoulders and also allows you to adjust the shape of any custom shoulders you
create. You will notice that you cannot adjust the settings when a predefined shoulder is
selected. You must press the new button to create a clone of the selected shoulder and then
you will be able to edit the settings for the cloned shoulder. You can also rename the cloned
shoulder once it is created by pressing the Rename button and delete the clone by pressing
the delete button. The predefined shoulders cannot be deleted.
Once you have created a custom shoulder, you can adjust the shape of the shoulder using
the power table controls. A shoulder is made up of a series of steps. Each slider bar controls
the laser's power level for that step from 0 to 100%. The first and last steps in the shoulder
are fixed at 0 and 100% respectively. You can vary all of the values in between to create a
desired shoulder shape. The numbers beneath the power levels represent the width of each
step in 0.001" (.0254 mm) increments; you can make each step up to .004" (.116 mm) wide.
You do not have to employ all of the steps to make a shoulder; you can use the check boxes
to deactivate steps to shorten the table. When you deactivate a step, the power level for that
step is automatically set to 100%.
Note: The maximum possible shoulder width is 0.064" (1.62 mm).

Clip Art Mode

This is a special mode that allows you to easily print many images from off-the-shelf clip art libraries.
Many of these images are made by combining many overlapping shapes and only print correctly if
converted to grayscale bitmaps. Be aware that this mode converts the entire graphic being printed
into a grayscale image, including vectors, and the black color job settings are used for processing.
Because of this you will notice that the color table is reduced to one color (black) when this mode is
selected. The dither pattern applied is the pattern currently selected in the dithering section of the
raster sub tab.

Reduction Mode

Raster Block Reduction Mode (also known as Print Growth Management), is specifically for barcode
engraving and adjusts the barcode elements for readability by removing pixels from the edges of
each element of the barcode being printed to adjust them for readability. This is necessary because
most barcodes are generated from barcode fonts so that the widths of the elements in the barcode
are not adjustable. This mode allows you to adjust the widths of the elements at time of printing to
make the barcodes more readable with barcode scanners. The Reduction Setup button allows you to
control the amount of reduction that takes place.
Reduction Setup Button
When you press the Reduction Setup Button the reduction setup window will appear and allow
you to adjust the amount of reduction that takes place in .001" (.0254 mm) increments.

Frame Rasters switch

A Frame Rasters feature is available in normal mode which affects the way rastered object are
processed in the laser system. When this switch is off the raster strokes the X axis makes when
laying down the pattern of dots on each line of the raster image can vary with the image. For
example, if you are engraving a triangular shape the tip of the triangle will be engraved with short
raster strokes and the strokes will get longer as the wider parts of the triangle are engraved. If this
mode is turned on, the longest raster stroke for the raster object being engraved will be determined
and all other raster strokes will be made equal in length to the longest raster stroke. This will increase
processing time, but can improve edge quality when engraving or marking at higher processing
speeds. Use this mode only if necessary.
