Background Image

The background image gives a visual representation of preprinted artwork, it is

not laser engraved. Click the ellipses (...) button to select the background image.

This image is display only and not produced.

Alpha Channel

Some products have areas that contain special features, e.g. a kinegram.

Depending on the material, these areas may be more sensitive to laser energy

causing bubbling or delamination of product layers. To prevent this from

occurring the laser power must be reduced in these areas.

A grayscale image can be created that represents the laser-receptive area of the

product and is used to control the laser power of selected elements on an area

basis. In this image, white corresponds to full laser power and black corresponds

to zero laser power. Gray levels are used to vary laser power between these two

extremes. This is done by an alpha blending process and the image mentioned

above represents the alpha channel.

The image must be of the same size as your layout and is cur

rently limited to a

fixed resolution of 96 dpi (which is enough for this purpose). For ID-1 layouts, the

alpha image should be 324 x 204 pixels and for ID-3 layouts, the alpha image

should be 472 x 332 pixels. The image is aligned to the bottom-left edge (0.0 / 0.0

Coordinate) of the layout.

This power reduction only works with bitmap based laser elements, not

with vectors.

• Click the ellipses (...) to select an image to use for the alpha channel.

• To use this feature, an element’s Alpha Blending check box must be selected.

See Bitmap Settings tab of Element Properties.

• Select the emb ch

eckbox to embed the image in the layout. Once loaded, the

image is stored in the layout file. This is useful if the image might not be

persistent at the specified file path. If not embedded, ConCAD attempts to

load the image from the specified location every time the layout is opened. If

the file is no longer in the location, there will be an error when opening the

layout.

Guidelines

Guidelines that can be displayed on the front/back side are defined in the

respective lists by selecting Add Guideline, Edit Guideline, or Remove

Guidelines. The guidelines can be shown or hidden by using the View menu.

Units are in millimeters unless otherwise indicated.
