The prepress determines how the finished printed product will be look and is the responsibility of product’s quality. The main stages of prepress:
- Receiving the application and files from the customer in accordance with the established requirements.
- Preparation of an electronic layout for printing.
- Trapping and color separation.
- Making digital color proofs.
- Confirmation of digital color proofs with the customer.
- Layout proofs.
- Making a trial print proofs on printed matter.
Rotogravure printing provides the highest quality printing on
packaging materials with the ability to reproduce the smallest details and bright, rich colors.
The rotogravure printing technology enables uniform ink transfer when working with a
wide range of densities and at high speeds, which makes it suitable for use in areas that
require high image quality, such as publishing, packaging and labeling, securities
printing and decorative printing.
The durability of the circulation mold of printing cylinders
makes rotogravure printing an ideal technology for high-quality printed product with very
large runs that are constantly being repeated, providing savings compared to other
processes. The linear type machine is “ROTOFLEX SUPER – 1000” allows printing up to 10 colors at one-sided and 9 + 1 paints for double-sided printing. The picture after printing is continuous, alive, repeating any halftones and transitions of the original image.
Laminating – the process of gluing two or more materials of different types. The laminate, which has obtained by this method, has a set of properties and increased barrier properties derived from all materials that have been used.
Laminating allows you to use interlayer printing. In this case, the paint layer is between the
materials, which excludes contact paint with the product, and protects the printing from damage.
At present, in MONOPACK. There are two systems of lamination, solvent and solventless.
Solvent lamination – solvent based adhesive system.
Solventless lamination – an adhesive system without solvent.
Advantages and disadvantages of lamination systems:
Solventless system (without solvent). For lamination, one- or two-component glue is used which has been applied in a slightly warmed state. The equipment allows evenly apply adhesive with a minimum grammar of 1 to 4 g / m2. A significant advantage of lamination without a solvent is the exclusion of tunnel drying required in the solvent lamination process. The disadvantage is the impossibility of making packages that are subject to sterilization, pasteurization, and hot filling.
Solvent system (with solvent). The most commonly used two-component adhesive with a solvent. Solvent systems are used much less often solventless, but they certainly have a number of advantages. Solvent lamination technology has traditionally been used in the production of highly barrier laminates. The solvent system produces materials suitable for sterilization, pasteurization, hot filling, as well as for packaging with enhanced chemical resistance.
1. The process is the cutting of roll materials.
2. The process of forming and gluing the rolled web into the sleeve, applying vertical
perforation, tearing tape and winding them on the sleeves, as well as further single-
piece cutting (if necessary).
3. The process of cutting and gluing cone for ice cream (cornet).
4. The process of packing finished products.
