Large Poster Printing

Custom Poster Size

A large poster is any one that cannot be printed on standard cut digital printing paper due to its size; in other words, any poster print with a custom size larger than 12.75″ x 18.75″.

You are able to enter any size for large posters, in fractions of an inch, up to 50″ wide and any length. Poster printing of 4.5 feet by 10 feet is conceivable and possible.

How to enter fractions of an inch into your poster print order

Because you can order any custom poster print size, it is important to enter your numbers correctly. This can be done by converting the fraction of an inch from your tape measure to a decimal point.

This is done by dividing the top number into the bottom. For example, if you want to print a width of 27 5/8″, enter 5 ÷ 8 into your calculator and get .625. Then enter 27.625 in the order form for the width of your poster printing product.

Pricing for large posters

Whereas with bulk posters the price is for each sheet of paper, with poster printing and other large format printing, pricing is by the square foot.

The quantity discount is also calculated by the square foot, so one very large poster may be the same price per square foot as the total area of lots of smaller ones.

CMYK Colour

Custom posters are printed in CMYK colour. Artwork submitted in RGB format are converted to a printable format. This will happen in one of two ways:

  1. if you submit a .png file that the machine cannot read, it will be converted to .pdf to send to print
  2. the rip software will translate the RGB colour to CMYK and send colour detail to the machine.

Either way, if your artwork is not saved as a CMYK file, you may notice slight differences in some tones.

If you are concerned, please request a sample proof to be viewed in the print shop.

Poster printing paper stock

Large format posters are printed in full colour with eco-solvent inks on high quality, matte surfaced poster paper. In other words, your custom posters are easy on the environment and recyclable.

Paper thickness

Posters printed on 7 mil paper have a quality feel. A “mil” is 1/1000 of an inch, basically the thickness of a heavy text stock.

The thickness of the paper makes the poster strong, and the smooth finish and quality inks are scratch resistant.

Big posters require large artwork

High resolution or vector artwork is required for a file to be enlarged. Even then, enlargement more than 600% is significant and will result in a loss of quality in many files.

Please check your file properties before submitting.

Advertising with large poster prints

Larger posters are ideal temporary signs, advertisements, or event announcements. Because they are printed on paper, poster messages are perfect for indoor use.

You can post these lightweight posters  with any double sided adhesive, or place them in snap frames designed just for that. Contact us if you want to know more about the frames.

Large format posters are a great way to display your personal artwork and photography.  Panoramic photos taken with your cell phone turn our surprisingly well.

Poster Calendar

For large printed advertising that will be viewed all year, consider printing a poster calendar.

A simple full year calendar view printed on an attractive poster with your company information on the bottom will stay on the wall all year long.

High gloss, water resistant poster

Alternatively, large format posters can be printed on self adhesive vinyl.  While it is essentially a big sticker, the vinyl can give your poster a high gloss or matte water resistant surface.

Mounted poster printing

For a free standing poster that can be placed on an easel, we print posters on self adhesive vinyl and mount them on foamcore. The result is beautiful and ideal for your next presentations or trade shows.

Get print-ready artwork without the headaches

Every print job must start with a useable digital, print ready file.  Here is a list of the most common issues with artwork that is not print-ready:
  • It has no bleed – your background image/colour should extend beyond the size of the finished product by 1/8″ all the way around
  • Document is sized improperly – an 8.5″ x 11″ file cannot be easily used for a half letter or 4″ x 6″ postcard, or for a 12″ x 18″ poster
  • Images used in the artwork are pixelated – all images should be 300 dpi
  • Entire file is low resolution – your file should be saved at 300 dpi.  Many free online programs do not export appropriate resolution.
  • Colours are set to RGB instead of CMYK – in this case, the colours that are printed may not be what you are expecting
  • Contrast between background and fonts is inadequate – dark fonts do not show up against a dark background.  What works on a backlit monitor will not work in print
  • Fonts are too small – it is wise to print a version of your artwork on a home printer to see the actual size of the fonts before ordering.  Again, it may look great on your monitor at 500 times magnification, but not work when printed.
  • Fonts are not embedded or converted to outlines – this can cause fonts to change in the processing of the file, changing your entire layout and design
  • Content has errors
  • Content is too close to the edge of the design – allow a “safe zone” to accommodate small variations in the printing, cutting, and finishing
  • Crop marks are improperly placed – this is the same of not having bleeds
  • You submit multiple files – a double sided flyer file should be in one .pdf file, 2 pages, not 2 files
  • File is in the wrong format – pdf files should be submitted.  While we allow other formats, they have to be converted before they can be processed.   In many cases, that is quite difficult as the file can be changed by the process.  In other cases, the file is not compatible with our software or hardware (for example, none of our printers can print .png files!  They all have to be converted to a printable format first).
  • The artwork is an idea, something you had printed somewhere else, written on a piece of paper, or a bunch of image and text files that need to be assembled – there is lots of work to do to get the file you need.

Experience has taught us that most customers, and sadly, many professional graphic designers, do not understand how to create print ready files. In addition, many of the free products available for you to design for yourself, do not output print ready files.  In some cases, your file can be easily corrected, using the wide variety of (expensive and sometimes difficult to use) software that we keep on hand at the Laser Sharp shop.  If you are stuck, we can help.  Use Service Tiers table to select the support level suitable for your project.

Some Fine Print

  • The prices shown are charge PER PRODUCT ORDER.  In some cases, design elements created for one print job may be used in others; if so, you may be able to select Advanced artwork for the first product and Standard for another if elements created for the Advanced project are reused in the Standard one.
  • The price for the tier includes any or all of the checked elements.  In other words, if you only want to get files prepared to be sent to you in different formats, you need to select the Advanced option.
  • You need to use the the red “upload your print files” button to upload your pictures and support documents.  There is a text box for you to provide details.  The more detail you give, the more likely you are to get a fast turn around on your support.
  • You are responsible for securing the legal rights to use any images, texts, or logos.
  • You are also responsible for planning the marketing strategy and goal behind your artwork.  We provide services to create digital print files, we do not develop your marketing program or create content.
  • The pricing for Advanced has a “+”.  If you expect more of the designer, like for us to find pictures for your project or to write content, you will be asked to pay more.
  • An electronic proof is included with most options.  It is CRUCIAL that you review the proof carefully with the following in mind:
    • Each support tier comes with a limited number of revisions.  Given that, when you receive your proof, take time to consider EVERY change you will want before you ask for revisions.  Any revisions requested over the limit will result in a request for further payment before they are made.
    • The colours you see on your screen and phone will not (necessarily) be an exact match to the final print.  If you are concerned about colour, it is your responsibility to request a printed (hard proof) before approving the job.
    • Any error in the content or colour mismatch is your responsibility once you give the go ahead to print.  If the designer has made an error, he/she may never know (for example, if a price or phone number is incorrect), so it is up to you to catch that before it goes to print.  There is no refund or credit given for reprints – the designer’s mistake is yours now.
    • Production WILL NOT START until your approval is received IN WRITING and in the requested manner and wording.  Don’t phone and tell us to go ahead.  Email and tell us to print the proof version sent to you (by file name) or that proof X is not approved because this specific change needs to be made (please don’t just tell us you don’t like the colour!!).
