Agenda
 Why the need for a new digital plate making system.
 Understanding the limitations of modern CTP for Flexo.
 Introducing the Kodak Flexcel NX system.
 Introducing a breakthrough for Aqueous and Solvent printing.
 Business benefits.
Why invent a new digital flexo plate system?
 Flexo had a significant constant growth in packaging printing
since its introduction more than 75 years ago
 Digital flexo plates have been available for over a decade
 Flexo is now the leading print process for packaging
The challenge
Yet the most common complaints from
printers are still based on technical
limitations such as:
Unacceptable color matching to
proof and other print processes.
Inconsistency in the process
Unpredictability of results
job-to-job, and run-to-run
Flexo has to move forward to meet the
demands of brand owners and printers
Typical LAMS plate processing and results
File
Original tonal values 0% - 100%
Flexo tries to match
the original image
Without adjustment it
fails, leaving hard
edges
Plate
Uncorrected plate loses dots in highlights,
first dots at 10% area (example for 150lpi)
Print
Uncorrected print shows hard edge
Typical LAMS plate processing and results
File
Bump is applied to compensate highlight loss,
tonal range is compressed to 10% - 100%
A bump curve is used
to set the minimum
dot size
Plate
Compensated plate values range 2-3%-100%
Flexo tries to match
the original image
Print
Final compensated print
LAMS plates: a renown limitation
Effects of “round top” surface
 Measurability
 Inking & Printing predictability
Kiss impression
= ? % dot
3 µ Impression
= 4% dot
• How do we calibrate?
• What will it print?
Considering a
typical LAMS
dot profile
cross section
6 µ impression
= 9% dot
Results with the Flexcel NX System
File
Original Tonal Range 0% - 100%
Original offset
separation
Plate
Plate tonal range 0% (0.4%) – 100%
Up to 300 lpi – 120 lpcm
Result: gravure class reproduction of the original

How do we solve this with Flexcel NX
LAMS plate vs. Flexcel NX plate
 Flexcel NX System achieves stable flat top dot structure
 Provides consistent structure and repeatability on press

Boosting ink transfer in flexo printing
An additional Flexo challenge
Especially when printing on films
with solvent inks:
 Insufficient density
 Uneven ink laydown
 Narrow color gamut
Limitations in these areas mean:
 Flexo print lacks the visual impact of gravure
 Print that lacks brilliance
 Many special colors are used
 Split plates are common
 More expensive inks and higher volume anilox
What’s wrong with traditional digital flexo?
Efficient ink transfer is always an
issue, especially with solvent inks on
flexible substrates
 Split plates and high volume
anilox are often required to
get required opacity
 Poor ink transfer throughout
tonal scale contributes to
reduced color gamut
 Voids in printed solids
reduce the visual impact

Previous attempts to improve ink transfer
Plate surface texturization has long
been thought to hold the key to
improved ink transfer:
 Mechanical methods have
been tried
 Plate coatings have been
tried
 Digitally imaged plate cell
patterning has been tried
But none have delivered dramatic
improvements or been consistently
successful

Explore new opportunities tomorrow
 Do more with process color printing
 Make co-printed designs a reality
 Open the door for gravure class quality
 Optimize your press
 Print up to 175 lpi in regular production
 Give brand owners greater design freedom
Designs that were previously only achievable
with roto-gravure are now in regular flexo
production with Flexcel NX Plates.
Co-printing designs can restore profitability to
short runs jobs.
