Convert to Image
With this node you can convert an object or a group of objects to an image equivalent.
It can be used to:
- Reduce the complexity of a layout, label or package.
- Clean up sliced background images in PDF documents created with an application that exports the proprietary file format to PDF
The node has the following configuration options:
- Input File: here you can select the input file. Select the pencil to open Expression Builder.
- Convert Selection Only: if you select this checkbox, only a selected group of objects will be converted to an image. If you leave this checkbox unselected, any object in the file will be converted to an image.
- Guarantee Visual Correctness: if you select this checkbox, the knockout objects lying on top of the selected objects will be taken into account during the conversion, which creates a knockout on the objects converted to image. If you leave this checkbox unselected, knockout objects lying on top of the selected objects will be ignored while converting the selected objects to image.
General
- Resolution: here you can select the resolution of the image that will be generated.
- Oversampling: here you can select the oversampling ratio. For example, if the resolution is set to 300 ppi and the oversampling ratio to 2, the images will be converted at 600 ppi and downsampled to 300 ppi.
Shadings
- Noise: here you can define how much noise should be applied to the shadings
when converting to image to prevent them from banding on the image setter or proofer.
However, noise may cause screen defects when using hybrid screens in which conventional
and frequency-modulated screens are combined. Therefore noise can be applied in certain
ranges, between certain percentages:
- Apply from 0% to …%
- And from …% to 100%
- Output: here you can select the output type.
Options:
- Postfix: if you select this option, you can define a postfix that will be added to the newly generated file. The new file will be placed on the same location as the original file.
- Custom: if you select this option, you can specify a path where the new file will be placed and a postfix that will be added to the new file. Select the pencil to open Expression Builder.
