You can remove the halftone screening data from a screened 1-bit TIFF file and convert this file into a continuous-tone 8-bit TIFF file. The resulting 8-bit TIFF file can be used in any desktop or image-editing software. Descreening can also be used to create composite content proofs.
You can choose whether to write out to a composite CMYK TIFF format or composite PDF with all spot channels retained by choosing PDF or TIFF from Preferences > Descreen > Descreen file format.
- From the File menu, select Descreen.
- In the Descreen dialog box perform the following actions:
- Clear the check box next to all of the separations that you do not want to include in the descreening process.
- In the Output resolution box, type the required resolution of the output file.
- To scale the output file, in the Scale box, type a scale value.
- To rotate the output file, in the Rotate box, select the required degree of rotation.
- To flip the output file, in the Flip box, select Horizontal or Vertical.
- To determine what type of resampling algorithm is used, under Method select Halftone or Linework, depending on the content of the files.
Or, to let TIFF Assembler Plus software determine the most suitable method, leave the setting at Auto detect. - To sharpen the resulting Descreen contone image, leave the Sharpen setting at Normal. Or, select None or Extra, depending on the desired result.
- Click Save.
- In the Save dialog box, browse to the location where you want to save the output file and, if desired, type a new name for the file in the File name box.
- Click Save.
