Small object protection
The Harlequin TrapProTM, object-based raster engine, available with the Harlequin® RIP, Eclipse VersionTM onwards, delivers outstanding performance. It adds the features demanded by top printers and publishers and is designed to trap jobs automatically. TrapPro in-rip trapping can be easily configured to accommodate different types of job or customer. Trap settings can be saved to reduce system time; improving both quality and consistency of trapped output.
Harlequin TrapPro is an object-based trapping engine that uses the Device-Oriented Display List that is generated in the Harlequin RIP. This allows the trapping engine to trap everything the RIP renders, with pixel accuracy, and with great speed. The traps are drawn with a brush and it maintains color fidelity and traps real device colors so trapping with extra grays is supported. Harlequin TrapPro provides the following benefits:
- An easy to use Graphical User Interface (GUI) allows the user to quickly configure the trapping parameters.
- Once the user specifies the parameters for trapping, the traps are automatically applied before the file is output to the media.
- Preview traps:
- After creating a trapset, a user can check that the traps are being generated as intended using the built-in Roam preview feature (or roaming in PPM)
- Monitoring in-RIP trapping:
- You can use the RIP monitor window to verify that trapping is occurring in the job, and check for quantity of objects trapped and their speed.
- The trapping itself is much faster than a raster engine; because it does not have to go via an intermediate raster just for the benefit of the trapping engine; the whole workflow is extremely efficient.
- In generating the traps, TrapPro uses the extra information in the Harlequin Display List which provides a significant advantage over using a pure raster. The traps are clipped to the objects from which they arose, eliminating problems such as mushrooming (normally associated with brush-based traps)
|Anamorphic traps: Anamorphic trapping is a method of compensating for different degrees of misregistration in the x and y directions in the printing process. Trapping compensates for misregistration, but TrapPro actually compensates for different amounts of possible misregistration in both axes.|
|Narrowed traps: There are cases where the full width of the trap does not fit into the available spread area. In these cases, TrapPro automatically modulates the size of the trap to cover a proportion of the available area. The user can adjust the default value. A 50% value is shown in the example below.|
|Sliding traps: When adjacent colors have similar neutral densities, TrapPro automatically slides the trap position from spreading the lighter color into the darker color.|
|Feathered traps: As an alternative to having a constant color across its width, a feathered trap fades gradually from the full trap color to the background color. The protection against misregistration tails off gradually rather than disappearing abruptly. The visual impact of a feathered trap is generally much less than a constant-color trap of the same size.|
