Graphics
The LASER machine acts like a black and white printer (black is engraved and white is not), so the photographs (bitmaps)
in a scale of grey or colours as well as multicoloured clipart images are transformed into smooth images. This is done when
the LASER machine reproduces the image. This process is very similar to the way magazine photos are printed, as well as
photos obtained from LASER printers
A conversion must be made by your software or by the printing drive of your LASER machine. The following paragraphs
describe the various conversion possibilities with the printing drive of the LASER machine in the normal mode
(image 1)
and rubber mode (image 2)
« Automatic »
(only normal mode - image 1)
is used to run the printing to convert the colours in the cliparts and texts (everything that is generated starting from graphic
forms and texts) to levels of grey so that it can automatically assign the adequate power to each pixel based on the level
of grey and proportional to the power assigned to the colour black.
The colours in the photos (bitmap format) are processed in the same way.
Engraving of the entire job is done in one scan. The engraving parameters (max power, speed etc.) are set by the colour
black.
« Filling »
(normal and rubber mode - images 1 and 2)
is used to process the colours in the same way as the automatic mode with a power range divided into 64 levels. For each
of these levels a specific filling is applied.
The engraving parameters (max power, speed etc.) are set by the colour black.
All the points are engraved with the same power (set by the colour black).
Engraving of the entire job is done in one scan.
« Black and white mode »
(only rubber mode - image 2)
is used to process the colours in the same way as the automatic mode for the cliparts and texts (everything generated
starting from the graphic forms and texts) and sets the limit of the image to 50% of black (power set by the user) for the
photos. Each pixel over 50% of black is converted to white (engraved) and each pixel less than or equal to 50% of black
is converted into black (not engraved). This operation is similar to a photo duplication process with a photocopier.
« User colours »
(only normal mode - image 1)
is used to run the printing to convert the colours in cliparts and texts (everything generated starting from graphic
forms and texts) from 8 basic colours set in the print drive interface. The other colours are converted to the closest
colour of these 8.
Engraving of each colour block is done separately with its associated engraving parameters.
The colours in the photos (bitmap format) are processed like in automatic mode. Engraving of the photo block is
effected after the last colour block with engraving parameters of the colour black.
« Negative image »
(normal and rubber mode - images 1 and 2)
used to run printing to convert an image into its negative image. All the objects which were filled with black and thus
engraved become images filled with white and no longer engraved.
« Photo mode »
(normal and rubber mode - images 1 and 2)
"Photo mode" scatters the pixels in a random pattern to represent shading. Each obtained dot will be engraved with the
same power (the power of the black color). The optical illusion of shades of grays appears due to the density of these dots.
Therefore the result will be the same whatever the material you use.
