DTP question - bleed and crop marks - any help appreciated!

I'm designing something for print by a professional publisher (A4 size booklet, 20 pages). As such, they have requested a 3mm bleed and crop marks.

I've managed to sort these out successfully, but have one question.

As the booklet is A4, saddle stitched in the middle, I'm assuming it'll be printed on A3 paper and folded down the centre. Therefore, do I need to create a bleed on the side of A4 which will be folded and will form the centre of the booklet?

I hope that made sense, all help appreciated.

Thanks!!

Best to talk with the printers themselves for a definite answer; it depends on how they are printing them. I used to email over PDFs of each individual page and they would then put it together when I did this as part of a previous job; but my guess is yes if you are doing each page individually, but no, if for example you are having pages 2 and 19 printed as one image.

Does that make sense?

the printers are quite possibly the most unhelpful people I've ever come across. Someone I know did this job last year, and they charged an extra £100 to "fix" crops/bleeds, and haven't yet replied to my emails about this

I'm making the pages individually but yes, I suppose pages 2 and 19 will be printed on 1 A3 sheet.... they want the final product as a pdf so obviously I'll end up with a 20 page pdf document, but don't know if it'll make a difference whether there is a bleed on one long side of each page...

Someone with more experience will hopefully chip in; but I would go with the bleed; after all, there is the staple and the overall width of the folded paper to be taken into account.

Where in UK are you as I know of a decent/helpful printers in West Yorkshire

its for a uni society event so has to be printed by media services at leeds uni

don't think a random printing company will appreciate me pestering them for technical help if I'm not going to be using them for printing!

If the end result will be an A4 booklet, then I would have imagined it'll be printed on oversized A3, hence them wanting crop marks for guillotining down to A3 for stitching.

It's been years since I had to create documents with crop marks, but as suggested earlier the print company is your best buddy on this one.

that's exactly how I image it'll be done. if I was sending the file to the printers as oversized A3 pdf , then it wouldn't be a problem but because I'll be sending it as a 20 page oversized A4 file, I'm a little confused

as I said, will email printers or call them

What you want to do is make a pdf of all the pages, ensure that you have an extra 12mm all round when you print your pdf's and give it 3mm symmetrical bleed in the settings. That way they can set up the imposition themselves but you will have done your job as each page will be print ready. Also ensure that you are printing CYMK and not composite RGB.

When I send files to the printers - many times a day, each A4 page is 234mm wide by 321mm tall - which is 210mm wide + 12mm on each side and 297mm tall + 12mm on each side.

What packages are you using for making the pdfs and doing the design work?

Also if your uni are doing you in for £100 charge for minor corrections you really should be using somewhere else! Even for society stuff.

thanks, I've nearly finished and gonna email a copy for the proof in the next few days so will see what they say.

have to use uni printers as payment is all done through internal orders (society rule or uni rule... not sure)

designing on microsoft publisher and converting to pdf using adobe acrobat 8, not the most professional software but remember, it's all amatuer!

also, why cymk and not rgb?

Well be prepared for a lot of grief with Publisher - it doesnt work seperations at all well, usually outputting black text as 4 colour text which makes the text very blurry and bold. Publisher is not a professional tool at all, and doesn't output postscript files.

As to why CYMK instead of RGB - the printing process is in CYMK and RGB will be colourshifted into CYMK which can leave more than a few suprises like your colours changing or in worst case scenario (which I've seen working with printers for years) dump the colour files and makes everything monochrome (ie all your nice colour pictures come out black and white).

I've had customer supply files in .pub format and usually its a total pain in the erse to get sorted, could be worse... could be word files.

Your best bet is to print a pdf using Acrobat and use a press setting for the pdf and hopefully the resolution will be ok, and that acrobat takes care of the separations.

well in the output settings for adobe, I use "high quality print". Also, I made posters this way for the same event, and they've printed well so I'm not overly concerned..... anyhoo will see when I get the proofs next week
