Decorating printing

The conditions to be met in decorative printing are particularly demanding. Decorative papers for gravure and flexographic printing are used to produce laminated plastic sheets. Pigment selection is a matter not only of the type of resin (melamine or polyester), but also a function of the processing method. 

P.Y.12 types are used in packaging gravure and flexographic inks for their reasonable price, but they can also be utilized in aqueous printing inks, provided they are sufficiently fast to light. They cannot be applied as decorative printing inks to laminated paper. 

DIN 16 524 solvent blend (Sec. 1.6.2.1). While the pigment lacks butter and paraffin fastness, it is completely resistant to soap. P.O.5 is not used for metal printing or for decorative printing. 

The printing ink industry uses P.Y.120 primarily for decorative printing inks on laminated melamine and polyester resin sheets. In terms of lightfastness, 8% gravure prints in 20 and 40 pm cells on such plates correspond to step 8 on the Blue Scale. Plate-out is not observed. P.Y.120 is insoluble in monostyrene and acetone (Sec. 1.8.1.2). 

Various disazo condensation pigments are utilized in decorative printing on laminated plastic sheets. They are also applied in a number of special-purpose media outside the above-mentioned groups, such as oil colors for artists and crayons. 

The list of applications also includes decorative printing inks for melamine based laminated plastic sheets. It should be noted, however, that P.B.15 1 may not be used in decorative printing inks for polyester-based sheets, because the pigment... 

The list of applications also includes printing inks, in which P.Gr.36 is tinctori-ally weaker than its copper phthalocyanine counterparts. For comparison, 1/3 SD letterpress proof prints containing P.Gr.36, printed at standardized film thickness, require approximately 26% pigment, while only 17% of P.Gr.7 suffice for the same purpose. The fastness properties exhibited by P.Gr.36 in prints, as in paints, closely resemble those of P.Gr.7, including the phototropic behavior of decorative printing inks for melamine-based laminated plastics sheets. 

Within the plastics area it can be used in rigid and plasticized PVC. The list of applications includes packaging and decorative printing inks. 

The list of applications also includes decorative printing inks for laminated plastic sheets based on melamine or polyester resin. The required fastness and performance properties are very good the pigment does not, for instance, color the clear sheets. 8% gravure prints (20 pm cell depth) equal step 8 on the Blue Scale for lightfastness. 

Decoration, printing thanks to the polarity the adhesion is better but a pre-treatment such as corona discharge is necessary. 

Overlay Paper. Overlay paper is a-cellulose paper of high purity, with substance weight in the range 20 to 80 g m-2. An essential feature is the refractive index, which is virtually identical with that of melamine-formaldehyde resin hence, after lamination—when all the fibres of the paper are wetted and consolidated with resin devoid of air—the overlay becomes transparent. It forms a durable, hard, clear layer to protect the decorative print layer below. 

Any specific performance requirements i.e. during use, including closure efficiency, warehousing, distribution and display, durability of identification/decoration/print, etc. 

Vibration also leads to friction, causing abrasion and possible text damage. Certain surfaces (plastic, enamels, etc.) or decorated/printed items must avoid contact with abrasive materials (wood, fibreboard, paper and board, etc.) and be overwrapped in a less damaging material, e.g. PE/PP film, bags or an air cap. 

After fabrication, e.g. two-piece metal cans, glass and plastic containers, collapsible metal tubes. Containers are manufactured and then printed or decorated by a secondary process. Since material and container shape impose certain restrictions, i.e. process used, design limitations, etc. some fabricated containers may use labels, printed sleeving, etc. rather than a direct decoration/printing process.
