CONTROLLING THE PROCESS FOR MAXIMIZED QUALITY & PRODUCTIVITY
INK & VARNISH PROPERTIES:
Low Tack.
High level of solubility and rewetting.
Low Viscosity. DIN # 4 Cup, 18–24 seconds. Zhan # 2 Cup, 21–25 seconds. Zhan # 3
Cup 13–16 seconds.
Low volume <5.5bcm. or <8.5cm3.
High resin levels.
High pigment (dry solids) levels.
Color sequence – Dark to light (K-Black1, C-Cyan2, M-Magenta3, Y-Yellow4). pH –
High to Low (K-9.5, C-9.3, M-9.1, Y-8.9, V-Varnish 8.7)
Color & pH sequence – Dark to Light (K-Black1, C-Cyan2, M-Magenta3, Y-Yellow4).
pH – High to Low (K-9.5, C-9.3, M-9.1, Y-8.9, V-Varnish 8.7)
Temperature maintained at 70˚ Farenheit (21˚ Celsius)
Peristaltic Pumps
PLATE PROPERTIES:
Good release.
Good release, low to no surface tack
<35˚ Shore hardness.
Cushion back for resilience.
RECOMMENDED ANILOX & DOCTOR BLADE SPECIFICATIONS:
Water Based Ink & Varnish:
>360lpi (lines per inch) or >140lpc (lines per centimeter) for water based.
<5.5bcm or <8.5cm3 for water based.
UV Varnish:
<300lpi (lines per inch) or <120lpc (lines per centimeter) for UV.
>7bcm or >11cm3 for UV.
Preferred Doctor Blades:
Angle 30˚ USA (60˚ Europe) - RMB Duroblade* (Formerly BTG)-Ceramic Tipped Steel.
45˚ Angle - Tooled Steel.
NOTES: 1-Board temperatures should be above 70˚ Farenheit (21˚ Celsius) for optimum
drying performance. 2-Although gloss levels are substrate hold-out dependant, actual
production trials have shown that optimum gloss level of water based varnish are achieved
at <5.5bcm or <8.5cm3. We recommend, therefore, that anilox rolls chosen for application
of water based varnish should apply similar or the same volume as the printing units. While,
UV gloss levels are optimized at >7 bcm or 11cm3. 3-UV gloss levels can be enhanced by;
A - Warming the UV varnish to a temperature of approximately 100˚Fahrenheit or
40˚Celsius. Powerblanket at www.powerblanket.com, supply an electrically heated blanket
that wraps around the UV varnish container. B - Utilizing a peristaltic pump to minimize air
bubbles in UV varnish. 4-Ensure all vacuum transfers are ‘Dryer Ready’.
