Now, due to the strong development of the Internet, there are more and more two-dimensional code, bar code and query code labels used by businesses with traceability, anti-counterfeiting, lottery and other functions. Part of the digital information of the labels of these variables needs to be kept secret before the sale of goods, so scratch-ink printing is needed on the labels. Today I will share with you the actual combat case is the edge analysis of this paper label in the manufacturing process of die cutting size.
Requirig more data variables, such labels would normally use digital printing machine printing. In terms of typesetting, we usually maximize the quantity as possible in order to save more costs. From typesetting, digital printing, silk screen printing and scraping ink, the production department carried out step by step and there was no problem. We thought that we could finally deliver according to the customer's delivery date, but unexpectedly there was a problem in the last link of die cutting.
Die-cut offsets result in ragged edges of labels! What should I do if such a quality problem occurs near the customer's delivery date? We all know that customers with such quality are definitely unacceptable. Fortunately, we have a lot of experience and think of a remedy right away, otherwise there will only be problems with the order.
It's well-known that paper before printing has certain water content. Especially for coating digital printing type of package materials, it uses water-based solvent the most so that material moisture content exceeds bid. In this condition, what we use is medium fragile paper. It has extremely high plastic coated materials bibulous rate, so it has big expansion ratio causing the situation that it severely shrink in the screen printing scraping ink after oven drying, which finally result in die-cutting knife die and the copy can not be centered. Here is a brief introduction of label printing machines manufactured by Loyal.
1. Purpose of paper cup printing machine:
Suitable for printing paper, paperboard, thermal paper, high-grade sticker labels, etc.
2. Characteristics of paper cup printing machine:
The product has a wide printing range, no ink pollution, high economic benefits, printing speed and other characteristics.
Main motor adopts imported electric frequency conversion speed regulation.
Automatic tension control is adopted for unwinding.
Ultrasonic deviation correction is used to guide paper.
Partial printing uses ceramic roller with long service life, wear resistance, corrosion resistance and other characteristics.
Printing unit adopts 360-degree external alignment adjustment. The print unit can be separately connected or released so that other print units can continue printing.
Each printing unit is equipped with infrared drying device.
The machine has die cutting function.
The machine measures automatically.
Parking roller can be automatically detached to ensure low speed dynamic transmission preventing ink dry.
Paper rolling, printing, automatic infrared drying, die cutting, rewinding completed in one time.
