L Shape Height Adjustable Desk Lifting slide table is a kind of work table that can be raised or lowered by electric or manual means, which can be used for office, study, painting, writing and other activities. According to different classification standards, lifting and sliding tables can be divided into the following types: L Shape Height Adjustable Desk,Work Office Lift Table,Automatic Desk Lift,Adjustable Lift Desk Suzhou Herstar Medical Technology Co., Ltd. , https://www.htstandingdesk.com
This became a hot spot at this year's DRUPA`2000 Expo. The on-machine-to-plate systems introduced by these press manufacturers are the product of international cooperation. The basic model is for printer manufacturers to take advantage of their own advantages in the printing press field and work with prepress manufacturers to use the on-press imaging technology of these manufacturers to work with the plate supplier to use the appropriate media system. Presstek and CreoScitex are the two most influential providers of on-machine imaging technology.
Compared with off-line direct plate making, the biggest advantages of on-machine plate making are quick plate making and short preparation time before start-up, which is very suitable for short-printing market with short delivery time. This is one of the main reasons why direct-to-platemaking has been developing rapidly in recent years. However, the machine-to-plate system can only use its own printing plate. That is, the inseparable plate-making and printing functions of the machine-to-plate system or the specificity of the equipment have hindered the large-scale industrialization of the technology to some extent. application. Fortunately, this issue has already begun to be resolved today.
For example, the SpeedMaster 74 DI on-machine plate-making system launched by Hei-delberg in cooperation with CReO uses CReO's thermal scanning imaging technology (40 W/CM2 infrared laser) and Agfe's direct thermal plate Thermolite. Changes, without post-processing, allegedly take 3.5 minutes.) Since Thermolite is a water-based offset printing plate, SpeedMaster 74 DI is equipped with an ink and dampening water system similar to a conventional water-based offset press. Therefore, it is also possible to use the traditional PS version. In other words, the SpeedMaster 74 DI is a dual-use printer that can be used as both a direct-to-plate system and a conventional offset press. The Oliver-474 EPII-DI system introduced by Sakurai Graphic Systems uses the integrated infrared laser scanner ProFire from Presstek and PearlGOld, a direct thermal media with water, and is therefore also a dual-purpose machine for direct-to-machine and traditional PS versions. Printing press system. The specificity of platemaking and printing functions is no longer an inevitable result of the mechanism version technology.
Due to the fast and easy plate-making process required in the plate-to-plate system, imaging techniques and media systems without post-processing are often used. The pioneering technology is Heidelberg's DI technology, which uses PReSSTek's infrared laser thermal imaging and thermal ablation waterless offset plate on-machine direct imaging systems. Other imaging systems began to appear, but thermal imaging systems, especially those that do not require post-processing, and do not produce contaminated thermal imaging systems, such as thermal phase change imaging systems, thermal wax transfer systems, etc., are still the preferred system. .
Komori's direct-plating plate system, code-named Project D, uses CreoScitex's 240-beam IR-LD laser head, and uses thermal plates without post-treatment provided by companies such as Agfa, Kodak Polychrome, and Asahi Chemica1. Can be controlled within 4 minutes. (To be continued)
1. Functional classification: lifting sliding table can be divided into single motor, double motor and three motor and other different types, with different lifting speed and bearing capacity.
2. Operation mode classification: the lifting sliding table can be divided into pneumatic and electric operation modes, and the moving operation can be realized by pushing buttons.
3. Classification of sliding way: lifting sliding table can be divided into two types with wheels and without wheels. The table with wheels can easily move the position, while the table without wheels is more stable.
4. Desktop material classification: The desktop of the lifting sliding table can be made of different materials, such as wood, metal, glass, plastic, etc., each material has its characteristics and application occasions customized.
5. Size classification: The lifting sliding table can be selected according to the height of the user and the size of the required working space. The common sizes are small, medium and large.
In short, choose suitable for their own lifting sliding table need to consider many aspects of factors, such as function, operation mode, sliding mode, desktop material and size, in order to meet their own work needs and personal preferences.
How to make plates directly (top)
Before and after the DRUPA'95 expo, the on-machine direct platemaking technology was only introduced by Heidelberg. It used Infrared laser thermal imaging and thermal ablation waterless offset printing plate direct press imaging technology of Presstek, namely DI printing machine (Direct Imaging ). There have been two series of printing presses that have been introduced to the market, namely the familiar GTO-DI and QuickMaster-DI. After five years of development, it can be said that basically all the well-known offset printing press manufacturers have introduced on-machine direct plate-making systems.
