<strong>What</strong> <strong>is</strong> <strong>DuPont</strong> <strong>Cyrel</strong> ® <strong>DigiFlow</strong> ?<br />
• <strong>DuPont</strong> <strong>Cyrel</strong> ® <strong>DigiFlow</strong> <strong>is</strong> a workflow enhancement that allows full<br />
support of solid screening programs in a standard digital workflow.<br />
• The <strong>DigiFlow</strong> exposure unit creates a<br />
controlled atmosphere which allows<br />
optimum formation of screened solids<br />
while retaining all the productivity and<br />
cons<strong>is</strong>tency of the digital workflow.<br />
• Solid screening programs will allow<br />
flexographers to achieve higher solid ink<br />
density when required with either digital<br />
<strong>Cyrel</strong> ® or digital <strong>Cyrel</strong> ® FAST plates
How Does <strong>DuPont</strong> <strong>Cyrel</strong> ® <strong>DigiFlow</strong> Work?<br />
• Digital <strong>Cyrel</strong> ® <strong>is</strong> imaged on an Esko CDI in the normal<br />
manner. During imaging, screening patterns such as<br />
Esko Groovy screens, HD Flexo Microcell or others<br />
are applied to the plate being imaged.<br />
• The <strong>DigiFlow</strong> Exposure unit incorporates a modified exposure<br />
chamber that creates a prec<strong>is</strong>ely controlled atmosphere during<br />
the main exposure process.<br />
Th<strong>is</strong> controlled atmosphere allows 1:1 reproduction between<br />
the LAMs layer and the plate, which results in hybrid digital<br />
dots and screened solids in the fin<strong>is</strong>hed plate.<br />
• The <strong>DigiFlow</strong> exposure unit <strong>is</strong> also fully supportive of the<br />
standard digital workflow. Simply return to standard<br />
operating mode for regular plates with standard digital dots<br />
• <strong>DigiFlow</strong> <strong>is</strong> fully compatible with both solvent process and<br />
<strong>Cyrel</strong> ® FAST digital plates

So what’s the difference between DigiCorr & <strong>DigiFlow</strong>?<br />
• <strong>Cyrel</strong> ® DigiCorr was specifically<br />
developed to reduce fluting when<br />
printing with thick digital <strong>Cyrel</strong> ® plates<br />
on corrugated board.<br />
• The DigiCorr workflow exposes the<br />
digital <strong>Cyrel</strong> ® in a nearly pure nitrogen<br />
atmosphere.<br />
Standard Digital – 34L/cm<br />
<strong>Cyrel</strong> ® DigiCorr – 34L/cm<br />
• Th<strong>is</strong> results in a hybrid dot with a broad<br />
base, steep shoulders and deep relief<br />
that <strong>is</strong> ideal for the corrugated market.
<strong>DigiFlow</strong> optimized for Flexible Packaging<br />
and Tag & Label<br />
• The need in the flexible packaging and tag & label markets was to<br />
maintain all the benefits of the digital dot and utilize the ex<strong>is</strong>ting<br />
workflow while incorporating the benefits of new solid screening<br />
technologies<br />
• <strong>DigiFlow</strong> mixes prec<strong>is</strong>e amounts of oxygen and nitrogen to create a<br />
controlled exposure atmosphere that optimizes solid screening while<br />
maintaining small and cons<strong>is</strong>tent highlight dots.<br />
• Digital <strong>Cyrel</strong> ® and digital <strong>Cyrel</strong> ® FAST plates with solid screening and<br />
exposed in <strong>DigiFlow</strong> exhibit significantly higher solid ink density with<br />
a much smoother appearance, and higher overall print contrast.
Digital <strong>Cyrel</strong> ® - Technology Evolution & Workflow Options<br />
Digital HD Flexo Solid Screening<br />
Analog<br />
• Good Quality<br />
• Complicated PrePress<br />
• Cut-Backs required<br />
• Resolution limitations<br />
• Incons<strong>is</strong>tent<br />
• Minimum Dotsize <strong>is</strong> the<br />
limitation<br />
• Excellent Quality<br />
• Simplified PrePress<br />
• Expanded tone range<br />
• Higher Resolution<br />
• Open reverses<br />
• Dot sharpening produces<br />
smaller minimum dot<br />
• Bump curve <strong>is</strong> necessary<br />
• Excellent Quality<br />
• Fully compatible with<br />
current workflow systems<br />
• Flip of a switch to change<br />
between digital and <strong>DuPont</strong><br />
<strong>Cyrel</strong>® <strong>DigiFlow</strong> workflows<br />
•1:1 reproduction<br />
• Improved transition to zero<br />
• Improved highlight<br />
performance compared to<br />
conventional screening<br />
• Higher solid ink densities<br />
and smoother ink laydown <strong>is</strong><br />
achieved due to a high<br />
linescreen pattern on solids<br />
• Oxygen inhibition limits solid<br />
screening performance.<br />
Varies with plate type &<br />
durometer.<br />
<strong>DigiFlow</strong> HD Flexo Solid Screening<br />
• Improved solid screening<br />
resolution for higher SID and<br />
very smooth ink laydown<br />
• Performance improvement<br />
seen with both Groovy<br />
screens and MicroCell<br />
screening.
<strong>DuPont</strong> <strong>Cyrel</strong> ® <strong>DigiFlow</strong> <strong>is</strong> a digital workflow enhancement designed to expand<br />
the capabilities of digital <strong>Cyrel</strong> ® and digital <strong>Cyrel</strong> ® FAST. The <strong>DigiFlow</strong> exposure<br />
system enables 1:1 image reproduction when a screened solid <strong>is</strong> beneficial, and<br />
with the flip of a switch returns to the standard digital exposure workflow whenever<br />
that <strong>is</strong> the preferred solution.<br />
