UV Drying is critical to the development of improving your print order. GEW is the worlds largest supplier of UV drying to the printing industry. Now Pressology is partnering with GEW to introduce their advanced LED UV Drying system into Australia as a retrofit system to your printing press. With a short payback period, Pressology & GEW improves your production 11 ways.

  1. No marking when perfecting and no set off sheet to sheet
  2. No powder spray required
  3. No waiting for long periods of time for sheets to dry
  4. No need to stack protective pallets in delivery
  5. Very little heat generated or stock distortion with water cooled LED UV lamp heads
  6. No loss of colour from adsorption or evaporation
  7. The ability to print on non-absorbent stocks with greater colour impact
  8. Sheets can be returned to the press for further printing
  9. Sheets are ready for guillotining, folding, etc. faster
  10. More vibrant colours with a wider colour gamut and sharper dot
  11. Enables you to achieve closer match to you digital printing.

Detailed Info

Print on plastics and other substrates

LED UV polymer inks allow successful printing on almost all stock types as they will adhere well to non-absorbent materials like PE, PET, PU and synthetic paper.

LED UV brings added value, increased product diversity and new product offerings with coated and uncoated papers, plastics and foil laminated sheets all becoming a possibility.

Sharper dots, vibrant colours, higher quality

GEW’s LEDs achieve sharper dots, more vibrant colours and a better quality finished product.

Inks are dried instantly, allowing no time for dot gain or absorption. This gives particularly good results on uncoated stock; colours stay vibrant, punchy and sharp. Furthermore, ink dries to a durable polymer to maintain the quality and longevity of the product.

Eliminate spray powderand sealers

LED UV curing avoids the need for spray powder on the press. This eliminates the widespread contamination and associated time-consuming cleaning.

As LED UV inks and varnishes are 100% cured directly after the LED lamp, marking and scratching are eliminated, thus removing the need for machine varnish or sealers.

Instant drying and faster job turnaround

Instant drying of inks enables immediate finishing and much faster dispatch of jobs. Sheets can be perfected, folded, cut or bound right away, reducing work-in-progress and significantly shortening lead-times.

LED UV gives the printer a competitive edge, enabling litho quality to be achieved in the same turnaround time as digital work.

No heat

Unlike H-UV or traditional mercury lamps, LEDs emit very little infrared heat towards the substrate.

This avoids common heat-related issues in sheetfed printing such as high pile temperatures, curling of heat sensitive stock materials and loss of moisture in paper: printed sheets remain crisp and fresh as new.

Increased productivity and machine up-time

Instant on/off switching means that machine up-time is increased, there is no time waiting for the lamps. In addition, the LeoLED has no moving parts so there is no downtime to replace shutters, reflectors or lamps. Maintenance costs are significantly reduced.

Expected lifetimes of 20,000 hours guarantee trouble-free printing for years to come.
