Which Is Better: PS Plate V CTP Plate

In the printing industry, the PS plate mainly refers to the aluminum plate used for printing, which has two types: positive PS plate and negative PS plate.

CTP plate has several meanings: computer to plate, computer to press, computer to paper/print. Here we refer to computer to plate. It is an imaging technology used in modern printing processes. In this technology, an image created in a Desktop Publishing (DTP) application is output directly to a printing plate.

There are three types: photopolymer plates, siverhalogen plates and thermal CTP plate. Thermal CTP platemaking technology is currently the most mature, stable, and effective platemaking technology.

The PS plate and CTP plate has been developed in China for over one decade. Haomei Aluminum has comprehensive range of aluminum plates for making PS plate and CTP plate. The rapid development of the enterprise in recent years has contributed to a rapid increase in production volume, which basically meets the growing needs of offset printing plates.

How Much Do You Know About Aluminum Mirror Sheet

Aluminum mirror sheet is the aluminum sheet processed by rolling, polishing and other methods to make its surface appear like a mirror. It is widely used in lighting lamp reflectors and lamp decoration, solar heat-collecting reflective materials, interior building decoration,etc.

For meeting the requirements of wide application, aluminium mirror sheet also have rich colors, which is generally divided into basic color and metallic color. The basic colors have: red, orange, gold, green, cyan,purple, black,etc. The metallic colors have: titanium gold, champagne, red copper, rose gold, stainless steel color,etc.

Which kinds of aluminum alloys are suitable for manufacturing mirror finish aluminum sheet? There are two main kinds: 5xxx aluminum alloy sheet and pure aluminum sheet. The classic ones of 5xxx aluminum sheet is 5005 aluminum sheet and 5657 aluminum sheet. 5 Series aluminum plate belongs to the more commonly used alloy.

It is often used in aviation, such as aircraft fuel tanks and also widely used in conventional industries. It belongs to the hot-rolled aluminum plate series and can be used for deep oxidation processing, therefore it is a good choice for making mirror anodized aluminum sheet.

The classic pure aluminum plates are 1050, 1070 and 1085 aluminum sheet. Among all the aluminum plate series, 1 series aluminum alloy has the most aluminium content, which is over 99.0%. Its production process is relatively simple and its aluminum sheet price is relatively cheap. It is the most commonly used serieds in conventional industry.

You can make a preliminary screening from these two aspects when you decide to buy polished aluminium sheet. Certainly, there are also other factors influencing the quality of mirror polished aluminum sheet like processing craft. We will discuss this topic in the following articles.
