Proofing

You check your artwork - our online proofing system will do the rest. If any proofing issues appear, we’ll tell you immediately. And if our system cannot resolve them, our print experts are ready to help.
 

Downloadable Proof

The Downloadable Proof is the closest representation of how your files will appear in print. Downloading this proof will highlight issues that may not be apparent in the Virtual Preview or Artwork Thumbnails. It’s available when you’ve uploaded all your print files (i.e., every thumbnail in your Artwork tab contains a print file), indicated by the document symbol next to the Preview button.

Viewing your artwork with a professional PDF reader like Adobe Acrobat will help ensure optimum print results. PDF files aren’t editable but demonstrate how colours and text could look in print. On-screen colours can vary between devices and depend on your settings, so contact us if you see differences.

You can download the proof by:

  • Clicking the Proof button > Wait for the checkmark to appear > Click again to open the Proof > Click the Download button (arrow pointing down above a straight line). 

Or...

  • Right-clicking the Proof button and use the ‘Save As’ option to save your PDF file > Open and check your file on your device with the Overprint Preview instructions (see ‘How To View Proofs with Overprint Preview’ section below).
 

Professional Proof

Professional Proofs are digital PDF proofs that undergo a detailed analysis called preflight to prepare the files for press, resolve errors and facilitate smooth production. They’re free and necessary for orders over $5,700. They are not colour-accurate, and requests for extra proofs are subject to additional costs. Once you receive an email confirming that your professional proof is ready for inspection, you can review your work and adjust errors before production.

Your prints will only enter production once you approve your Professional Proof. If you reject your proof, contact us and explain why so we can assist with corrections. Rejecting your proof can also affect shipping dates.

 

Artwork Thumbnails

Artwork Thumbnails are small, low-res depictions of your files and how they could look in print. 

The Thumbnails will show:

  • Trim boxes: the green lines show where we’ll aim to trim your prints.
  • Bleed box guidelines: the blue guides ensure your artwork extends past the trim lines to minimise unprinted lines from appearing once cut to size. Please supply your artwork files with bleed before upload.
  • Gutter boxes: the pink/purple shaded spaces indicate what may be lost or partially obscured by the binding.

Thumbnails appear in your Artwork tab and help you check page sequence, layout, and orientation. One thumbnail is equivalent to one page on Bound items like Books, and one thumbnail corresponds to one side on Flat items like Posters

Removing the guidelines will also ensure your files have sufficient bleed. Click ‘Show guidelines and legend’ in your Artwork tab, and the box will reappear when you click it again. Warning and error messages may appear throughout file-checking, but you can resupply your files with bleed or contact our team for advice. If you approve files without resolving the issues flagged, we cannot amend them during production.

 

Virtual Preview

The 3D virtual representation of your artwork will appear in a flipbook or flat-sided format without guidelines (click here for an example). It depicts your work in lifelike quality and ensures your pages and artwork are present and appear in the correct order for viewing only. The Preview button with an eye symbol is at the top of the Artwork tab. You can also share your work with others by pressing the Share button at the top of the preview (arrow pointing to the right inside a box).

 

How To Proof Print Files

  • Manual Check: Review all issues our system flags and manually check every page. Our system will highlight most technical printing issues, but we combine our technology with experienced print experts who will quality-check your work before and after print.
  • Images: We will warn you if your artwork is under 100dpi. Missing this step can delay your print work going into production, so please double-check your files before proceeding.
  • Bleed: Ensure your artwork extends beyond trim lines. Position important content outside quiet areas and gutter margins on Bound items except for Layflat, Staple and sewn-bound items.
  • Text: You must embed every font on your original file and reupload. Also, keep an eye out for missing text and odd text characters. And always proofread and spell-check your print files. 

Friendly reminder: Please ensure your content is legal, copyright-free and doesn’t breach our Terms and Conditions.

If you, or a Mixam print expert, make any changes to your artwork files or print specifications, be sure to review the Thumbnails, Preview and Downloadable Proof again. You can edit your files as much as you like - so give yourself plenty of time to make changes until you are satisfied with the outcome.

You are responsible for preparing every element of your print files. We work from the understanding that when you confirm your order, you’ve checked your files, and you are happy for us to print them as they are. But our print experts can always help you resolve issues before sending your work to print. To avoid common print issues, follow our print checklist.

 

How To View Proofs with Overprint Preview

We recommend turning on the Overprint Preview in Adobe Acrobat Reader when viewing your Downloadable Proof. Overprint Preview will give you a more accurate representation of your final prints on-screen, so please check the downloaded version thoroughly before confirming your order. 

This function will also prevent colour loss, and you can see any transparencies mixing with spot colours. We recommend setting this as a default so you can see your work in high definition. To turn on the Overprint Preview, complete the following steps:


On a PC: Go to EditPreferences > Select Page Display > Under Page Content and Information, the Use Overprint Preview dropdown menu, confirm or change to be set to Always.

On a Mac: Go to Acrobat Preferences Page Display > Under Page Content and Information, the Use Overprint Preview dropdown menu, confirm or change to Always.

 

Colour Matching

You should upload your print files in CMYK colour mode. Our system will automatically convert any RGB files to CMYK. However, this can cause colour variations, so design your artwork using CMYK.

We cannot guarantee that the colours on your screen will match the colours on your final prints. If colours are critical, contact us, and our print experts will do their best to help you achieve colour-accurate work where possible. (Below: RGB is left, CMYK is right).

  

 

Shipping Dates

If our team flags any issues with your print order and bring these to your attention, it will delay the printing process until they’re resolved. We are happy to work closely with you to fix these issues. However, to avoid delays, please check your work carefully before uploading. For more information, refer to our Shipping and Delivery Support Page.
