Inline Coating Unit

for Heidelberg GTO 52

Properties of the
LACO Inline Coating Unit
-  Increased Productivity of your Heidelberg 52 press with attached coating unit through printig and coating in one sheet
   passage on the last press tower.
-  Refinement of the printed sheets by increased gloss and contrast.

-  Increased protection of printed sheets against mechanical influences. If UV-coatings are used, even a protection
   against influences is present.

-  A wide range of usage and application possibilities.

-  Water based protective coatings are fast dry on the surface. The result of this is:

               1. time saving by an earlier possible perfecting/processing of printed and coated sheets
               2. effectively reduction of spray powder possible
               3. safe production through reduced blocking, sticking and gluing tendencies
               4. double sided production possible after short waiting time
               5. no additional time required to eliminate pile problems like mentioned above

-  Effect coating applications possible like Drip-Off method (special overprint varnish + high gloss water
   based coating) or Hybrid method (special overprint varnish + UV-coating)

-  A
LACO coating unit can be combined with an LACO IR-dryer. The use of such an integrated IR/Hot-Air Combination
   dryer enables:
               1. Gloss and High-Gloss water based coating applications inline (wet-on-wet)
               2. often a further spray powder reduction possible
               3. a further increase of production safety and productivity
- Pre-Conditions to attach a LACO 52 coating unit to a Heidelberg 52 press with low pile delivery:

               1. A Plus Version (numbering and imprinting unit/preparation) must be already installed in all
                   Heidelberg presses which get upgraded with
LACO coating unit.
               2. An Interface STA Adaptor must be installed in all Heidelberg Printmaster PM 52 and Speedmaster
                   SM 52 presses. In Heidelberg GTO 52 presses an Interface STA must only be present in press
                   models manufactured after DRUPA 2000. Older GTO 52 presses built before 2000 must not have
                   an Interface STA Adaptor to attach a
LACO coating unit.
