Impress produces special-shaped cans for Heinz

Heinz has reactivated its Karvan Cevitam fruit juice product profiled can, which replaces the brand's traditional round cans.
This new three-piece deformed printing can is the result of the collaboration between Heinz and Impress's R&D centers in France and Impress's plants in the Netherlands.
Heinz Company stated that the container is made of fine-grained tinplate and is blown into a specially designed mold to form a special-shaped can. The cans are easy to stand out on the shelf, easy to hold by hand, and easy to handle and display the quality of the product. The design of the arc will produce lithographic design effects on the tank body, which will give the product a bright and vivid image, and now 70% of the fruit tanks have improved the method.

Guides of Exposure

1) Wire cloth and stain mesh shielding is strong, therefore, the desired exposure time to be longer. Rough wire mesh and fine wire mesh to the long exposure time required.
2) is preferably a vacuum state in order to ensure the sharpness of the halftone pattern and the sawtooth and biting teeth phenomenon, let halftone to ensure full contact of the backsheet and the photosensitive layer should be remembered that the exposure to dyeing mesh time longer.
3) in the use of the tunable light source (position adjustable), In order to ensure uniform and reduce the biting teeth phenomenon, the halftone exposure distance is preferably 1.5 times the diagonal of the pattern by the sun or the diagonal length of the halftone 1.5 degrees.

4) lack of exposure, often brought to the screen can not be reused or with trachoma and serrated. Flush, if the network version of the squeegee surface sticky and soft feel, indicating that the halftone underexposed, i.e. not enough light reaches the squeegee the surface of the photosensitive layer, so that the photosensitive layer can easily be washed away. Meanwhile, the underexposed, the photosensitive layer is softer or the photosensitive layer is washed away. The network version is not resistant to mechanical abrasion and solvent resistance.
5) Sometimes, the underexposed Screen also take remedial measures. : Gently rinse off the screen, will be washed away by the softer photosensitive layer, rub with White, and then drying the screen, and the last exposure.
Note, the squeegee side facing the light source.
6) As the temperature and humidity changes with the seasons, it is recommended that every few months to be one step exposure test. At the same time,
Proofing light source will change in the long-term use of the process, and also because of the power storage device may not be able to provide timely supplement. Periodic step-by-step exposure test so you can know the use of the light source and the light bulb, and when given replacement.
7) if necessary, replace the lamp.
8) Diazo or dual processing photosensitive paste, there are often latent image (shadow) appeared shadow color change after exposure.
