UV- Fields of Application Market segments Graphic Arts Industry Marktsegmente Converting Automotive industry & industrial applications 6
UV Applications in the Graphic Art Industry Web Applications Narrow Web Applications Metal Decorating Sheet Fed Offset 7
Advantage of UV printing No VOC No skinning of ink No spray powder Less waste Immidiate drying UV Effect printing Full pile printing In line coating Hi gloss Printing on foil 8
Market Trends UV Significant trend for more inline effects High Gloss, structures/drip off etc. Special applications provide the opportunity differentiate from the market e.g. plastic cards, mouse pads, plant tags, inmould labels etc. The interest to use UV for commercial production is constantly increasing More short-run jobs and just-in-time delivery Print buyers often demand maximum flexibility 9
To be considered Higher investment cost UV system, extractions, press preparation Higher productivity, special applications and effects Learning process during start-up time Different handling The UV Transfer Center can offer start-up training and support Increased energy consumption and costs SLC, CMK, URS, ELC, modular end-of-press, InstantStart, Smart guard, LEUV Higher prices for UV inks and UV coatings Higher profit margin for special applications and effects Characteristic odour caused by photoinitiators, monomers and coated papers Can be minimized with good quality consumables and substrates 10

Equipment Components 12
Spectral Energy Distribution UV-C Imperative for the polymerization of of printing inks and varnishes for a complete curing. UV-B Supports and maintains the triggered off reactions and ensures a better curing because of of longer waves. UV-A Responsible for the curing of of very thick layers. 13
Heatmanagement Water cooling URS Reflektor Water cooled shutter Air cooling 14
is about how to guide the UV light from the UV lamp to the substrate. No reflector = more than 50% loss of UV light Reflector = minimized loss Heat removal for heat sensitive substrates URS reflector 15
URS Reflector / Heatmanagement URS Reflector A system of di-electric layers is applied on an aluminium profile. only UV light is reflected; the IR rays will be absorbed Very robust for a long lifetime 16
Reflector technology Reflexion characteristics Reflexion [%] Al/Aluminium CMK Reflector URS Reflector 17

Energy Efficient Equipment
more³ Seal of quality for energy efficiency, tested safety, services corporate slogan more than UV product label e³ With our new slogan more³ we combine our traditional values with the IST product label e³ for environmentally friendly and efficient systems. 24
UV end-of-press system for sheetfed Energy minimized UV printing Developed specifically for sheet-fed printing applications Highest process speed Optimized energy efficiency 2 instead of 3 Two of the new EOP units can now produce the same excellent curing results as previously achieved by three EOP units (each with 200 W/cm lamps). Possible energy savings up to 33% 25
Application Training
Training course KNOW-HOW IS THE SUMMARY OF ALL THE BAD EXPERIENCE there are other ways to built up know-how. understanding the process and the technology is a key for success IST METZ offers training courses, dedicated to UV Printing 27
Quality through expert Advice UV Transfer Center Beyond the hardware the UVTC also delivers the brainware 28
LEUV = Low Energy UV
LE UV Application Mainly commercial application, but also Packaging and Foilprinting possible Best result with high reactive UV inks Fastest Curing time with limited energy but highest gloss (over 90 GP) Maximum Machinespeed with immediate drying 30
Spectral Output 31 Fe-Lamp @ 140 W/cm, OF 31 Relative Spectral radiance
Polymerisation Binder Pigment Photoinitiators Free radicals 32
LEUV Equipment
Space requirements of the components Example of a one lamp equipment Cabinet 0.48 m² Exhaust air/ Heat exchanger 0.72 m² combination cabinet Water distribution plate UV-Unit below footboard inside of the machine In total 1.2 m² 34
Why LE UV? Advantages Immediate Drying Immediate further processing Inline high gloss/drip off finishing No powder Immediate protection from abrassion No protection varnish necessary No color changes through absorption effect Ozonfree Lamp 35
Flexibility LE UV can be obtained up to maximum 3 lamps Compact method of construction Control range from 80 W/cm bis 200 W/cm High gloss inline application possible Fast processing time, no waiting time for drying, low inventory costs Conventional inks, high reactive inks and normal UV inks in the same machine possible Immediate evaluation of color match with coating 36
Printing Examples
Classic commercial printing or LE UV Conventional LE UV 4-5 colours without coating Immediate Standard Products further processing Immediate Long drying drying time of the ink No High protection inventorycoating for fast turn Use of arounds powder No powder required 38
Classic LE UV job 2 4C Process colours Board 300 g/m² Glossy coated Format 63 x 88 cm Multi product job Used for Table display and special promotions 39
Advanced Commercial Printing or LE UV Conventional LE UV 5 6 colours plus coating Protection Coating coating not for fast necessary turn arounds Inline finishing (water possible based) In Use some of powder cases inline not required finishing possible No colour change through Use absorption of powder effect Colour change through absorption effect 40
Packaging LE UV Substrate: Printed: Front: Reverse: Board 300 g/m² double side printing BCMY + Effect varnish + Gloss coating + 1 lamp LE-UV in the delivery with 150 W/cm at full speed BCMY + 1 lamp LE-UV in the delivery with 150 W/cm at full speed 41
