Description

  The present invention relates to a printing apparatus, an information processing apparatus, and a management apparatus, and relates to a misregistration correction control method and apparatus, and a storage medium for storing them.

  There are roughly three types of selection of the range for correcting misregistration. This is the case where the object to be corrected is individually specified, the type of object to be corrected is selected, and the correction can be written for all objects without specifying anything. For the second and third, the processing unit is each page.

One page of data is spooled in the memory, and it is determined whether there is any overlap with respect to the designated object or all objects in the spooled data, and if there is, correction processing (trapping) is performed. In order to consider the data transfer order to the rendering processing unit, the processed data is also spooled to the processed data memory until the determination process and correction process for one page is completed, and the data transfer order is taken into consideration. The data for one page was sent to the rendering processing unit. At this time, the processed data is enormous in amount by adding corrected parts and the like in addition to the original object data, and requires a large amount of memory.

Load it. A system bus 12 serves as a data transfer path between the above-described components.

  This apparatus operates when the CPU 1 executes a basic I / O (input / output) program, an OS (operating system), and a misregistration correction control program described below.

  The basic I / O program is stored in the ROM 3 and the OS is written in the HD 11. When the power of the apparatus is turned on, the OS is read from the HD 11 into the RAM 2 by the IPL (Initial Program Loading) function in the basic I / O program, and the operation of the OS is started.

  FIG. 5 is a flowchart showing the flow of misregistration correction control in this embodiment. This embodiment relates to control of trapping processing in a printing system that performs misregistration correction processing (hereinafter referred to as trapping).

  In step S501, a job for which a print command has been issued is spooled to the spool memory page by page. In step S502, one object to be printed is selected from the spooled print job for one page, and it is determined whether there is an overlap with other objects.

  Next, the process proceeds to step S503, and if no overlap is found, the process proceeds to step S505. If an overlap is found, the process proceeds to step S504. In step S504, an appropriate trapping process is performed on the found overlap.

  In step S505, it is determined whether the overlap between all objects in the print job for one page spooled in the memory and the target object has been determined. If an object that has not yet been subjected to the overlap determination process remains in the spool memory, the process returns to step S502 and the above process is repeated. If the determination process has been completed, the process proceeds to step S506, and it is determined from the result of the above process whether the target object is an object overlapping with another object. If the target object is an object that does not overlap with other objects, the process proceeds to step S509. If the object overlaps with another object, the process proceeds to step S507.

  In step S507, the trap area (trapping part) and the target object obtained by the trap process are spooled in the processed data memory as processed data.

  In step S508, it is determined whether all the objects in the spooled print job for one page have been processed as target objects. If there is an object that has not been subjected to the above process as a target object, the process returns to step S502 and the above process is repeated. If all objects have been processed as target objects, the process proceeds to step S509.

  In step S509, data spooled in the processed data memory or data that has not been overlapped and has not been trapped and spooled is transmitted to the rendering processing unit. The processing described above is shown in FIG. An overlapping object is subjected to trapping processing and spooling processing, but an object without overlapping is not trapped but spooled and transmitted to the rendering processing unit.

  FIG. 7 is a flowchart showing the flow of misregistration correction control in this embodiment. This embodiment relates to control of trapping processing in a printing system that performs misregistration correction processing (hereinafter referred to as trapping).

  In step S701, a job for which a print command has been issued is spooled in a spool memory page by page. In step S702, one object to be printed is selected from the spooled print job for one page, and it is determined whether there is an overlap with other objects.

  Next, the process proceeds to step S703, and if no overlap is found, the process proceeds to step S706. If an overlap is found, the process proceeds to step S704. In step S704, an appropriate trapping process is performed on the found overlap.

  The process advances to step S705 to store the identification number of the object on the other side that has been overlapped and has been subjected to the trapping process.

  In step S706, it is determined whether the overlap between all objects in the print job for one page spooled in the memory and the target object is determined. If an object that has not been subjected to overlap determination processing remains in the spool memory, the process returns to step S702 and the above processing is repeated. If the determination process is completed, the process advances to step S707 to determine from the result of the above process whether the target object is an object that overlaps another object. If the target object is an object that does not overlap with other objects, the process proceeds to step S711. If the object overlaps with another object, the process proceeds to step S708.

  In step S708, the trap area (trapping component) and the target object obtained by the trap process are spooled in the processed data memory as processed data. In step S709, it is determined whether the object identification number is stored. If the identification number is stored, the process proceeds to step S710 and the object is set as a target object, and the process returns to step S702 to repeat the above process. At this time, this identification number is deleted.

  If it is determined in step S709 that the identification number is not stored, the process advances to step S711 to transmit the pooled data in the processed data memory to the rendering processing unit.

  In step S712, the processed memory used by the data transmitted to the rendering processing unit is released. In step S713, it is determined whether all the objects in the spooled print job for one page have been processed as target objects. If there is an object that has not been subjected to the above process as a target object, the process returns to step S702 and the above process is repeated.

  The process described above is shown in FIG. An overlapping object is subjected to trapping processing and spooling processing, but an object without overlapping is not trapped but spooled and transmitted to the rendering processing unit. Further, for overlapping objects, a group of overlapping objects is determined, trapping, spooling, and data transmission to the rendering processing unit are performed for each group.
