When designing a document in your layout application it is important to make sure preparing it correctly. Here is a check list of items to review your document before creating your final PDFs.

Please check the following items before sending out PDF files:

  • Document is at the final trim size.
  • No important design in 4 mm inside margin (type safety).
  • Bleed area around the page is 5 mm.
  • All RGB images are converted to CMYK and gray images tor Grayscale.
  • All images are at a high resolution (images below 150 dpi will fail preflight).
  • All fonts are included.
  • Spot color job: delete any unused spot colors from color palette.
  • 4-color job: convert all spot colors to process CMYK.
    • Keep in mind that some spot colors do not reproduce satisfactorily when built out of process.
  • PDF/X-1a preset or accepted preset is used when writing out PDF file.
  • Check final PDF in Acrobat with "Output Preview" and with "Preflight".
  • Review final PDF with enabled "Overprint Preview".
  • Review final PDF with "Separations Preview" to ensure expected color separation.

Common problems encountered in prepress:

  • Low resolution images or graphics

  • Background color or image do not extends to bleed area and white line can appear after final trimming.

  • Dark areas in images have exceeding ink sum (against the paper specification)

Use Acrobat tool "Output Preview" (Preview - Separations - Total Area Coverage).

NOTE: We always stop all exessive ink problems – for checking or for fixing. No automated preflight is able to decide error by object size – so it stops all PDFs. In printing only the objects with size bigger than 2 cm are risky – these should definitely be fixed. Thin lines or small shadows are not ricky so these released after checking. Finding out is it the minor or mayor problem is time-consuming human job. If there is lot of jobs per day then the queue can be long. Therefore it is the best solution when uploaded files were checked and corrected before sending.

  • Important design (heading, footer) is extremely close to the page edge and text damage can occur after final trimming. Leave 4 mm space.

  • Images supplied as RGB instead of CMYK

  • Small black texts are separated to 4-ink color (rich-black color, C-50;M-40;Y-40;K-80) instead of solid black (100% K) and therefore text readability is not perfect.

Use Acrobat tool "Output Preview" (Preview - Color warnings - Warnings - Rich Black). Or use this.

  • White text has overprint turned on. White will disappear in final product. .

  • missing overprint

  • Light text built of only one or two colors appear jagged when printed and text readability can be decreased.

  • Colored text smaller than 12 point is subject to misregistration and text readability can be decreased.

  • It can be difficult to read text over an dark image

  • Named colors is used instead of specific Pantone color numbers

  • Fonts are missing

  • The color of large shape is 100% K and it is overprinted.

  • The bleed around page is not symmetrical.

  • The inside cover ad design is not accounting with cover glueing technology (a.k.a. "hinge binding").

  • Layout is insufficently considered with the creep or missing of the manual shingling can result loss of border text, page number, distortion of image or uneven page border.
  • PDF is created with readers spread pages and this is not for imposition.
  • Skin tones are not correct and will turn to "greenish".
    Try to follow the recommendated LAB values. When working with CMYK values, try to follow this guide and the rule C/3=M=<Y & K=0.

  • Black ink text on metallic ink is not made knockout, because "knockout black" (CMY:1 K:100) is not used.

Please check the following items when reviewing the printers proof:

Proofing Checklist

A "Printer’s proof" is a ultimate preview of your press-ready file, allowing you to examine and confirm layout, text and content before your order is printed. We rely on your thorough inspection of proofs to detect and correct errors. While we do our best to ensure that every project is done right, only you can make sure all the elements are in place. Print professionals are still only human. We do sometimes make mistakes or miss ones in your the original material you submit. That’s why proofing is a vital part of the printing process.

Once you have signed of on a final proof, you are giving us authorization to print. After you have given us the approval to proceed, we will not re-print for any error you did not notice. Please Note: We will not proceed to print without your written approval of the final proof(s) provided by us.

Because creating a new proofs can create additional work for your graphic designer as well as the printer, it is important to note that changes and/or corrections you make to the project during the proof stage normally will incur additional fees to your final cost. If you have any questions or concerns please contact our Sales Manager for more information.

The following is a list of items to double check on printer's proof before authorizing the job to be printed.

Proof Checklist

  • Pages
    • Are all pages included in the proof?
    • Are the pages in the correct order and page numbers correct?
    • Are the page numbers on the content pages correct to the story pages?
    • Are all corrections made from previous proofs? Check the final proof against your last set of proofs to ensure the final corrections were made. 
  • Photos
    • Are all images/photos included and in proper placement?
    • Is each image in the right place?
    • Did any images break and/or disapper?
    • Are photos cropped correctly?
    • Are all photos facing the proper direction?
    • Do photos and graphics have good contrast?
  • Texts
    • Are all fonts correct?
    • Are there any missing characters or broken type?
    • Are sentences & paragraphs lining up the way you intend? Check for unintended hyphenation and spacing.
    • Make sure italics, bolds, etc are used where you wanted them.
    • Double check all names, addresses, email & web addresses, and telephone numbers
    • Double check spelling, grammatical errors and punctuation.
    • Is the text crisp and spaced properly?
  • Colors
    • Verify that spot colors are defined as spot colors and process colors are defined to separate as 4-color process.
    • Verify that the PMS colors are defined identically throughout all pages.
    • Check color placement and color consistency throughout the pages.
  • Layout
    • Are the margins and page alignment(s) correct?
    • Measure and verify the final trim size and check folds and folded size for accuracy.
    • Verify that bleeds (by amount desired by printer) extend beyond the trim marks.
    • Verify that the finishing elements; such as  varnishes, foilstamping, die-cutting, embossing, drilling and perforations are properly indicated.
    • Confirm the paper type, weight and color of the final paper stock.
  • Have you let someone else go over your proof with this checklist too? 
    • The more people who check your proof, the better. We want to make sure your project is printed exactly the way you envisioned it and we need your help.

Congratulations! You’ve taken steps to ensure that you are sending error-free, press-ready files to printer. While this list isn’t all-inclusive, following these simple steps will certainly decrease any chance of something going wrong with your files.

Digital colour proofs

We can print out calibrated colour proofs according to colour profile of your printing paper (colour profile of paper is used). Color proof isn’t like final product, this is only for checking colors. These are separate sheets. It isn’t stitched, it isn’t in final size, just sheets.

Product dummy

We do not create product dummies.
