SheetFed Benefits

In the process of working with numerous companies around the world on the case for adding UV and LED technology, AMS has developed a very thorough understanding of the return on investment (ROI) equation. LED UV printing in the sheetfed offset market has advanced rapidly and globally in the past several years – catching up with, and now even surpassing the performance of other forms of low energy (LE-type) and high wavelength or hybrid (H-type) UV curing. UV LED is now considered the fastest growing process technology for drying, protection and effects creation in the segment. Nonetheless, it remains important to understand how and if the benefits from UV LED translate into true gains for your offset printing operation.

LED Printing compared to Conventional Oil-based Printing

The following lays out the general structure of benefits typically seen from implementing LED for Sheetfed Offset Printers who are coming from a Convenional (Oil-based) printing operation with or without water-based coating:

  • LED Energy Cost Reduction over IR/Hot Air (typically 80%)
  • LED Reduction of Time and Cost Spent Dealing with Marking Issues
  • LED Elimination of Powder Contamination
  • LED Reduction and Re-use of Makeready Sheets
  • LED Reduction of Paper Consumption (perfecting presses)
  • LED Speed of Drying and Job Completion
  • LED Elimination of Water-based Coatings and Varnishing Costs
  • LED Reduction in Polymer Plates Consumption
  • LED Added Capabilities (higher value coatings, varnishes, substrates, effects, etc.)

LED Printing compared to Traditional UV, LE-UV, H-UV and HR-UV Printing

We hear it a lot from offset printers around the world… what’s better, UV or LED? Are the newer, low-energy curing technologies marketed under names such as HW-UV, H-UV, HR-UV and LE-UV viable? Or are they just a bridge to LED?

AMS is one of the only companies with field-proven solutions, patented technology and production customers running ALL of the flavors of UV energy curing in the market today, including UV LED, and has a vested interest in seeing all of them succeed. We are therefore able to present a clear, side-by-side perspective on the costs and associated benefits from one form of UV energy drying to the next. Process and business goals differ at each printing company. Our goal is to help you make the best, most informed decision possible before investing.

The following benefits are generally available from LED UV solutions compared to traditional Standard UV interdeck and end-of-press curing solutions, as well as to the many new variants of High Wavelength Energy Curing Systems (alternatively called Low Energy, High Reactivity, Additive, or Hybrid UV printing):

  • LED Energy Cost Reduction over H- and LE- type UV systems (typically 50%) and UV (typically 80%)
  • LED Fewer Lamps Required compared to traditional UV systems
  • LED Lamp Uptime and Maintenance Savings
  • LED Heat Reduction and Related Issues Savings
  • LED Paper Moisture Retention Savings
  • LED Instant ON/OFF and Wash-up Cycle Operational Savings
  • LED Mercury Risk Avoidance and Disposal Elimination
  • LED Elimination of Ozone Smell and Hazards
  • LED Bulb Cost Savings compared to UV (2,000 hrs) / LE-type and H-type UV (650 hrs) Replacement*
  • LED Speed of Installation and LOW UV Preparation Required
  • LED Ink Cost Savings over LE-type and H-type UV (not controlled by a single vendor)
  • LED Affordability (lower investment cost than LE-type and H-type UV systems, and even traditional UV systems depending on the configuration)

H-type UV systems and LE-type UV systems utilize Mercury lamps with Iron additives that degrade and lose curing energy faster than Standard Medium Pressure Mercury UV lamps. They are typically replaced every 650 hours.
