The texture of the slide print surface is extremely
important for optimal print quality and durability.
The print surface varies considerably between
manufacturers, color selection and coated (posi-
tively charged) versus uncoated surfaces.
They can even vary greatly from slide to slide in
the same lot. Colored print surfaces, other than
pure white, contain pigments that help the ink
spread evenly and adhere strongly.

3.3 Print specifications
Only standard specimen slides with imprint-
able colored edges (23) can be imprinted in the
Leica IP S (see Fig. 5 ).
Printing directly onto the glass is not possible.
Specimen slides with the following dimensions
can be processed: 76 x 26 mm, max. 1.2 mm thick.

3.3.1 Requirements for specimen slides
• To reduce the amount of glass dust and the
risk of mechanical failures, use only clipped
corner slides (45° angle on each corner, Fig. 5 ).
• Slides to be used in the printers must be
stored appropriately in closed containers and
protected from dust and moisture.
• Positively charged slides are inherently sticky
so they require special handling to insure reli-
able mechanical handling by the instrument.
• When the print job is complete, the printed sur-
face of the slide may be handled immediately.
Please be aware, however, that the special
ink is alcohol-based and exposure to alcohol
in combination with physical contact (rub-
bing) could cause the print quality to degrade
significantly.
Specimen slides with a white printed surface
should be checked for print quality and ink resis-
tance before purchase.
Some slides have been coated over the print
surface as well as the glass, which can create
problems with the adherence of the ink. These
slides should also be tested for print quality and
ink adherence before purchase.
