2 THE GUIDE FOR MACÆ/ADOBEÆ CREATIVE SUITE USERS Welcome to Champion Newspapers advertising help guide for artwork preparation. This is where weíll provide the information and application settings youíll need to produce correctly-speciﬁed artwork.

THE BASICS An ICC proﬁle is a ﬁle that describes how a particular device (in this case, a printing press) reproduces colour. Newspaper presses use a process called offset lithographyand this is very different to our magazine presses, which use the gravure process. The proﬁle also controls the Total Area Coverage (TAC) for CMYK colours and can be used to set the maximum ink limit. Newsprint is speciﬁed as 240% whilst gra vure magazines can be up to 360%. We can supply ICC proﬁles that match all of the press/paper/ink combinations used to print each of our publications.
We use international standards for newspaper and magazine printing, such as PDF/X-1a:2001 and ICC printing proﬁles supplied by IFRA.
PDF/X is a subset of the Adobe Portable Document Format (PDF) speciﬁcation that is intended to reﬂect best practices in graphic arts ﬁle exchange. The aim is to produce digital content ﬁle that will run through our prepress systems without requiring rework or causing errors and be printed predictably and correctly on our presses.
We want to help you create artwork that will meet our printing speciﬁcation and, most importantly, give you the results you expect.
3 SET UP YOUR APPLICATIONS This is the ﬁrst important step. It will save a lot of effort if you set the application preferences to match the destination printing conditions before you start work on a speciﬁc artwork. Luckily, thereís an easy way of synchronising all Adobe applications using Adobe Bridge, so youíll only need to do this once for each print condition.
Launch Adobe Bridge and go to Edit/ Creative Suite Color Settings. Load the relevant .csf ﬁle and click Apply. All Adobe applications are now synchronised using this setting.
Of course, youíll need to choose an alternative CREATE YOUR First, go to www.niadhelp.com and download the setting in Bridge each ARTWORK time you begin artwork correct ICC proﬁles for each publication.

embedded in imported graphics.
4 If you have been given a CMYK image of unknown origin, you should consider converting it to RGB ﬁrst. It’s really important to use the Relative Colorimetric rendering intent with BPC.
Illustrator vector graphics should use the same mechanical, colour and font speciﬁcation as InDesign.
Imported ﬁles such as images, graphics and logos must be created with (or converted to) the correct ICC printing proﬁle. Embedding the CMYK proﬁle is not the same - this assumes it will be used by the printers prepress system and this is not the case at NI. It’s recommended to start with RGB images. Open them with their embedded proﬁle if possible as most will contain their default camera proﬁle. Turn on CMYK Preview (View/Proof Colours) to simulate the ICC printing proﬁle end destination colour space. Simulate Paper Colour provides points are set when you use better accuracy on a calibrated display.... but prepare to be the HL and SH droppers in shocked by newsprint simulation! the curves or levels windows Crop the image to constrain it’s physical size and resolution, thus keeping ﬁle sizes low without affecting image quality. Use 200dpi for newspaper images and 305dpi for magazines. (note: 1-bit images should be 1270dpi for newspapers and 2540dpi for magazines) Open the Curves or Levels window and use the droppers to set the range (highlight and shadow end points) of the image. It’s OK to drop out to white paper for newspaper printing but gravure magazines require a minimum dot of 6-8%. Adjust the gradation (contrast, brightness). Convert to the destination CMYK. Since you have already set up your default Color Settings, it’s OK to choose Image/Mode/CMYK. Make any ﬁnal (minor) colour edits and apply some sharpening if required, taking care not to change the highlight and shadow end points. The ICC printing proﬁle has controlled the maximum TAC (Total Area Coverage) and you could force the ﬁle out of speciﬁcation with excessive end point adjustment. Save the image in any supported format and place in your InDesign document.
5 CREATE A PRINT-READY PDF FINAL DOCUMENT CHECK: - have you applied the correct Color Settings? - are your trim and bleed sizes correct? - are all your colours CMYK or Greyscale? - have all your images been converted to the destination ICC proﬁle? - are all document fonts on your system?
Using InDesign Go to File / Export and choose Adobe PDF format. Name your ﬁle and save. Select Adobe PDF Preset PDF/X-1a:2001.
Select ì Outputî to check the correct ICC proﬁle name appears in the Destination ﬁeld. If not, you must go back and set your document colour settings. Export your PDF.
6 The Adobe Flattener settings will affect quality if transparency has been used in your artwork. Default settings for PDF/X-1a are 1200ppi for line art and text, 300ppi for gradient and mesh. Higher resolutions may improve quality, especially for magazine publications.
Go to Edit / Transparency Flattener Presets and save a new preset. You can apply it in the Export Adobe PDF window (page 4) by selecting ì Advancedî and choosing the new preset. Consider saving several Adobe PDF Presets for future use.
Export your InDesign document as an EPS with these settings. Enter bleed values to match your document.
In Distiller, select preset PDF/X-1a:2001 and open the EPS ﬁle to distill your PDF.
7 CHECK YOUR PDF News International advertising delivery systems will preﬂight your PDF on upload. However, Acrobat Pro also provides a preﬂight that will give you a quick way of checking the PDF before you send it.
Preﬂight In Acrobat Pro, go to Advanced / Preﬂight and select the PDF/X-1a preﬂight. Note: this option checks against the 2003 standard but it will still return valuable information and help you diagnose potential problems.
Most importantly, take a look at your PDF using Acrobat’s Output Preview to simulate the printed result.
In Acrobat Pro, go to Advanced / Print Production / Output Preview Select the destination proﬁle (which should already be selected as your output intent if you have correctly set up your applications). Turn on Simulate Overprint - does anything disappear? If it does, go back and check your InDesign overprint settings. Use Simulate Paper Color for a more accurate softproof on calibrated displays.
