Trim marks show as short lines at the corners of each page, this determines where our guillotines cut the edges of your work. Guillotines are notoriously inaccurate and can in some cases cut outside of the trim area, so it’s important that your pictures fall outside of the trim marks so that you don’t get left with a white edge. We would always recommend extending your coloured areas that go upto the edge of the page to extend 3mm over the trim area, this way you will be assured that you don’t get white edges.
If you are creating the artwork InDesign, then you should create your spot colours in the Swatches Palette choosing to create a new colour and choose ‘Spot’ from the ‘colour type’ then choose from the colour mode either PANTONE+ Coated or PANTONE+ Uncoated
Find your colour and save it, you can then use this colour in your work. Any resulting PDF that has been saved with spot colours in the output file will reference the correct Pantone colours.
When you make a PDF the settings that you use are important for the output. Without all the necessary parts correctly formed in the PDF, it makes it impossible to output.
A font when loaded on your computer has all the glyphs that make up the whole typeface and all of the component signs and symbols, however when you make a PDF you have the option to embed fonts as a ‘Subset’, which means that it will only embed the characters used in the document. If you choose to embed the whole font set, it will make the PDF bigger but will include all characters even if they are not used.
We take your supplied PDF’s and put them through our Prinergy system which flightchecks and traps your documents (see trapping info below).
Once we are happy that your document is ready to print, we send an automated email from our server with a link to your documents – this can be opened in any web browser and is html5 based.
Once you have the browser link open, you will be able to see all of your pages, and be able to click a ‘Preview’ button to open a ‘Page Turning’ page view window. Insite can’t preview PDF’s but instead uses .jpegs at three resolutions (72, 150 and 300dpi) for different page views. The further you enlarge the page the higher the resolution, so if you want to see type or images at the full resolution then zoom to the maximum enlargement. Lower zoom levels may look slightly pixelated, but is meant for faster viewing.
You will also see two other buttons, which are for downloading a high-res and a low-res PDF’s (proofs) respectively. Please note that with the high res option it will download a .zip compressed folder with all of your pages in single page format. This is the way our Prinergy system operates and is unable to combine pages into a single document.
The download of a low res proof gives you two options; download as single pages (as with the high res option), and download as a combined file (all pages in one pdf). Both of these options are PDF’s with all images down sampled to 72dpi.
Once you are happy that your document is ready for printing, open the ‘Preview’ window and move your mouse to the right or left of the screen – a pop out window will then appear where you can sign off individual pages.
Alternatively you can ‘Approve Job’ – the pages with the button on the bottom right of the window. This will trigger a script that will mark the job ‘Approved’ back in our Prinergy server and will fire off emails to the Gemini Print co-ordinator in charge of your job. We then will then move that job into the print queue.
If you are having trouble with viewing the PDF’s correctly it might be that your Adobe Acrobat Reader or Acrobat Professional settings are not set up correctly to view ‘Overprints’. If so, please follow this short guide:
To view overprint in Acrobat Reader please go to the ‘Preferences’ and turn this function on – you will find it under the ‘Page Display’ and then ‘Page Content and information’. Choose to show ‘Always’ and then open the PDF. You might want to turn this off afterwards or choose to keep it on all the time.
By knocking a hole in colours means that there is a chance that if the print is not exactly in registration that you might end up with a white halo where the yellow and Cyan didn’t meet properly, so this is where trapping comes in. We add a border of yellow around the edge of the circle and over print just the border, this is such a small amount usually 0.15th inch but it’s enough that you don’t see the white halo.
Gemini Print is colour certified for ISO12647 which means that we can output to Proof/Plate/Press in a controlled environment using Fogra as our standard. We use Fogra39 for Coated output, and Fogra47 for Uncoated; these standards are measured, maintained and certified every year to ensure that our colour output remains constant.
To find out more about ISO 12647-2 colour standards view the ISO 12647-2 document from the official www.printcertification.co.uk website.
