(1) Mode
You can select from four primary mode settings, depending on your application or results you would
like to achieve.

Black & White mode
Select this mode when using clipart images or drawings with several colors, shades of gray, or many
outlines. This mode outputs in a method similar to that of a black and white laser printer. This
machine will interpret colored and shaded areas as 256-level shades of gray by producing a
halftone effect while engraving. Instead of engraving only solid lines, gray or halftone areas will be
a collection of dots with varying density.
The entire selected image will be engraved using a single set of power and speed settings (the
black pen from the PEN menu. Please refer to the next section of the details regarding the PEN
functions). The resolution and depth of these halftone areas can be adjusted with the DPI setting
found on the Options page. Please note that selecting the Black & White mode will add a new Raster
page to the menu. The Black & White mode dithering settings can be changed from the Raster page.
(Please refer to the Raster section below for details). Experiment with different dithering settings
to attain the desired results.
Tip
The Black & White mode interprets the processed image by the varying colors and shades. For the
best results, we suggest you convert the image to a grayscale image with your graphics software
prior to engraving in the Black & White mode.

Manual color fill
Select this mode when you would like to designate specific power and speed settings and link
them to certain colors of your image. The LV-290 printer driver allows a maximum of 16 pen
parameters to be set.
(2) Position
These selections allow you to control the positioning of the laser head after each job completion and
before the next subsequent job.

Home
Sets the position of laser machine carriage corresponding to the origin (top left) position of the graphic
software before and after processing each job. Therefore, the laser carriage will start a job from this
home position and return to the home position after completed jobs.
(3) SmartCONTROL Vision
Check the SmartCONTROL Vision box to enable SmartCONTROL Vision function. More detailed setting of
VISION function can be found in Chapter 5.3.3.
Output Preview
Users can use the Preview function to check a simulated output of the job. An estimated working time will
also be shown.
