Tin can manufacturing plant process design and control points:
1, Indian iron equipment at home and abroad mostly monochrome printers and color printing mainly due to the requirements of printing equipment and printing materials restrictions and customer-specific packaging effects, using the traditional manner as dichroic color effect may be related to printing Original customers by providing a difference of many, as well as the subsequent Indian iron production potential problems. To avoid multicolor printing overprint allowed, abrasions, color clear color is not bright, defective and so much more widely used Printing spot color alternative multi-color overlay, such as Pantone colors. In addition to many more outlets and coarse mesh back the main line, so that the total area of Internet access points to reduce the amount of the smaller printing dot gain. So separation is the key to print metal products.
2, Indian iron sample separation is both a model test is to advance the quality of Indian iron product analysis and understanding. Its copy method using traditional offset printing down mode. In the proofing process needs to stay dichroic film as a printing process control reference, so that the printing quality and color can be a true representation of the customer to confirm the proofs. Printing and because few are part of the final product, which is often part of the proofing various containers, cover classes and a variety of miscellaneous supplies machining process at the same time test the paint processability and matching. Therefore, in this process, we need to be processed into finished products, into the contents, namely forming tests, such as food cans To seal the tank, shelf life, freshness is a test.
3, Printing drawings secluded three factors to determine when the rubber roller arrangement tinplate product positioning rules and products used in the coating composition. Which means the rules tinplate locate seams, by the direction and size of the body they are print-making is based on product arrangement is based on product copy of a different nature which are arranged in different ways, in the process of determining the arrangement can be considered Printing The minimum acceptable size and the maximum size at the same time you want to make the most economical arrangement; rubber coating applicator roller is a tool for the need for internal coating methods are applied to the full version of the product coating, coated blank vertical, horizontal blank less coated products, coated products and three kinds of coating methods are commonly used for food horizontal blank white coating for coating vertical empty spray cans, cans and cover miscellaneous products are usually coated with a full version: on There are vertical blank light paint coating and two types of coating applied to the full version of the way.
4, for tanks, most of the same picture production class printing the cover, making a lithographic drawings based on the determined product groups into a negative or positive image, even the use of sun exposure machine plate. This allows for both print dozens of the same image in the production process using PS version on a sheet, the other with plain paper printing plate-making methods such as exposure time, developing, fixing, washing and so on.
5, since the thickness of the different uses of products and molding equipment for tinplate, tin layer, hardness and annealing methods have different technical requirements depending on the nature of products we above factors to be determined both to meet the printing requirements but also meet Cans , red boxes and other requirements, and determine the final printed surface.
