How to increase RIP prepress output level

SPNT explains the PS file. A large number of mathematical operations were performed. Therefore, a large amount of space is required to store intermediate variables, such as shape data, dot matrix information, and the like. If there is enough memory PSPNT will store this data in memory. But if there is not enough memory. This data will be stored in the Windows NT virtual memory, which is stored in the hard disk. It is well known that the memory access speed is more than 10 times faster than the hard disk, and these intermediate files are parameters that the PSPNT needs to repeatedly call once it is stored on the hard disk. Although PSPNT can work normally, the overall performance will be greatly affected. The PSPNT stores the results of rasterization (RP) using a mid-lattice, and then transfers the dot-matrix file to its connected peripherals such as imagesetters. The middle dot matrix of PSPNT is a very large intermediate dot matrix file that is stored on the hard disk as a compressed file.

It is precisely because the speed at which each hard drive needs to perform a great deal of hard disk access to the hard disk is critical to the efficiency of the PSPNT. The test data is displayed for the same computer 1300. When using a 7200 rpm SCS/W hard drive, the PSPNT speed is more than double that of a 5400 rpm old E drive. The speed mentioned here refers to the time from the start of the job to the end of the imagesetter output. From the current technology. The stability of SCSI hard disk is better than IDE hard disk, which is also very important for user stability. and so. It is recommended that you select a fast SCSI hard disk (7200 rpm or more) when installing the PSPNT.

Also choose a better SCSI card. For other RIPs, you also need to select high-speed hard disks and higher-level memory. Another issue worth noting is that Huaguang's Type 7 RIP is based on the Apple system. The use of memory by Apple and PC is essentially different. The use and management of the memory by the PC is based on a random allocation. The operating system allocates appropriate memory to each application that is open at the same time. No manual intervention is required. However, the use of memory by the Apple system is based on manual allocation.

Every application needs to manually specify the size of the required memory. We can allocate enough memory for each application. If we don't open it at the same time, we can greatly improve the efficiency of each application. Based on this feature. When we use the Huaguang 7 RIP for output, we can specify enough memory for RIP. This will increase the efficiency of RIP work. The author once encountered an ordinary four-color version with Huaguang seven-type RIP output, which actually took 2 hours, and later found out. The host has 256MB of memory, but the memory allocated to the RIP is only 92MB (this is the default setting for Type 7 RIP) and the memory allocated to the RIP is increased to 200MB. To explain this version again, it takes only 10 minutes.

In summary, output is a job that requires technology and experience to do this job. You must be familiar with our RIP as well as be familiar with various types of layout software. It is even more important to constantly sum up experience in practical work and improve the technical level in practice.
