How to calculate ink required for printing layer ?

Liquid Ink = 4 times of dry ink. Assuming 25% solid content in liquid ink.

Printing Layer – Pet

Film Density – 1.4

Film Micron – 12

Film gsm – 16.8

Job Sample Ink gsm – 1.2

Printing Layer Quantity – 300 kg

Dry ink required = (ink gsm x printing Quantity)/printing Layer gsm

= (1.2 x 300) / 16.8

= 21.42 (dry ink)

Liquid Ink = 4 times x dry ink (solid content of liquid Ink 25%)

= 4 x 21.42 = 85.68 kg (Liquid ink)
What is Mylar Film?
Mylar is actually the name of a popular polyethylene terephthalate (PET) film from DuPont Teijin FilmsTM.

Mylar is technically BoPET (biaxially-oriented polyethylene terephthalate).

It has been a prominent film in a variety of applications across
– electronics
– food packaging
– industrial specialty
– cast & release
– graphics markets

Due to its balanced tensile properties, good adhesion, excellent moisture and chemical resistance, and ability to withstand temperatures from -100°F to 300ºF.

Mylar® polyester films are ideal products for high volume, dependable industrial performance, where lower cost initiatives must be met.
What is Roll OD?
Roll OD or Roll Outer Diameter is a measurement of the distance of a straight line from one point on the outer wall of the Jumbo Roll, through its center, to an opposite point also on the outside.

Generally it’s measured in mm (millimeter).

for eg. Maximum Jumbo Roll OD should be 650 mm for Printing/Lamination Machine.

What is PET?

Image
Density 1.4 Polyester film is a high-performance, crystal clear thermoplastic made from Polyethylene Terephthalate (PET) resin. In comparison with other common plastic films, PET film has high tensile strength, excellent dimensional stability, low moisture absorption, and good retention of physical properties over a fairly wide temperature range. It also has superior UV resistance and excellent electrical properties, and good optical clarity. Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film. PET Film – 150°C (302°F) and as cold as -70°C (-94°F) Properties higher tensile strength excellent dimensional stability low moisture absorption good retention of physical properties over a fairly wide temperature range superior UV resistance excellent electrical properties good optical clarity high gloss good gas barrier moderate moisture barrier Application aroma barrier film (e.g. coffee and tobacco packaging) release films microwave print...
