  • Line Art/Disk Conversion
  • Halftone
  • Scanned Image
  • Image Retouching
  • Coloring Work
  • Color Conversion
  • Cover Process

Line Art/Disk conversion


Line art or line drawing is any image that consists of distinct straight or curved lines placed against a background, without gradations in shade or hue to represent two-dimensional or three-dimensional objects.

It is usually a single-color drawing (such as one made with a pen or pencil) with little or no solid areas, and no shading effect other than cross-hatching. 

  • Images are categorized into simple, medium, and complex based on details in the line art images.
  • The images in Raster format (line art or line and tone) are redrawn to improve the quality of the images for printer requirement.
  • The images in vector format are redrawn to improve the quality by following the steps listed below:
  • Changing the font style as per the specification received from the client.
  • Re-sized the images to match the text area.
  • Fixing the stroke, weight, and color (gray/CMYK/PMS/RGB).
  • Working on the pattern and embedded object to avoid pitstop error during printing.
  • Will convert images to gray/CMYK/PMS/RGB as per the specifications.

Further to the above steps, the images are relabeled for readability if the labels are illegible. The images may also be relabeled to maintain consistency.



A continuous tone image, such as a photograph, that has been converted into a black-and-white image. Halftones are created through a process called dithering, in which the density and pattern of black-and-white dots are varied to simulate different shades of gray.


  • If the image is in halftone it should be sized to match the text area.
  • The brightness, contrast, highlight, and shadows are fixed.
  • Blurred images are sharpened.
  • The images are cropped based on the specification or requirement.
  • The images are masked or straightened depending on the image details and client requirements.
  • Images are extracted from the Doc/PDF/PowerPoint/Online and converted into required format as per the client’s specification.

Image retouching

image retouching

  • Images are corrected by retouching and clone stamping:

RETOUCHING:  Unwanted dust is cleared.  Scratches are removed from the image based on the client’s requirement to improve the quality.

CLONE STAMPING: Any part of the image that is lost or damaged is corrected by stamping.  Unwanted parts of the images are obscured by stamping.

Coloring work


  • Coloring work is done for the gray scale line art images as per the client’s specification.
  • Single color image is converted to CMYK.
  • Selected color is applied in the relevant part of the images.

Color Conversion


Images are converted from a specific color to a required color based on the received specification.

  • Gray image to CMYK
  • CMYK image to PMS
  • Gray image to RGB color image
  • CMYK image to gray image (i.e. single color), etc.

Scanned Image

scanned ImageAn image that is extracted from scanned pages.

  • Images extracted from the scanned pages are processed to improve the quality.
  • Sizing is done to fit into the text area.
  • These images are retouched and cleared for unwanted dust.

Cover image Process


These are small images, logos, and bar codes that appear in the cover.

  • Retouching of the existing cover image
  • Creating the cover image as per the client’s specification
  • Generating barcode and QR code
  • Creating thumbnail cover image for online
  • Creating cover image for online
