E-print

If you need anything printed, e-​print is the best option you have, in terms of speed and price. I have worked with many times, and more recently on a regular basis. They have shops all over town, if you haven’t noticed. They are linked with another company called bannershop — clearly only doing banners.
How e-​print works, is that they are online, and you can download a program and submit everything online. Once you have submitted everything you need printed, someone from e-​print will give you a call to confirm your order, you pay, then the stuff you need will be ready in just a few days.
I think their printing facilities might be in china — not sure exactly, their call centres are definitely in china though, which is why they can support such low cost printing.
I have had a few problems with the people i dealt with in the past, basically you have to yell at them to get the stuff done. frustrating, i know. but has to be done.
After everything is confirmed, you can pick up in just a few days. It makes life so much easier, being in hk, everything needs to be done asap, and this is the exact service they provide — asap!
They print everything from pull up banners, flyers, promotional material, posters, business cards, basically anything you can think of, they can do. quite amazing in my opinion.

The best place for business cards.
E-​Print is a small print chain making business cards, banners, brochures, stamps (as in chops, not postal). They have a number of convenient locations including Sheung Wan and Wan Chai, as well as an online service, but some ordering processes are only in Chinese.
The best thing about E-​Print is its simplicity. Yes, you can get business cards printed on textured cream paper using specialist inks — remember that scene out of American Psycho? However, unless you are CK Leung, who cares what the paper texture on your card is like, so long as it has your name and details!
The best E-​Print service is their standard business card service. For HKD55 you can get 300 matt cards, or for HKD70 the same quantity but laminated so they are slightly waxy. I go crazy and spend a whopping HKD90 for 300 UV spot laminated cards, which have my company logo artwork glossy and raised — fancy! Check out their website for the prices, they are very very good, but do be mindful of where the price breaks come (and check the costs which are not per box but per order). You may for example be better off buying 5 boxes or 10 boxes, but nothing in between, as the cost of 6 boxes is the same as 10 boxes.
Turn around times are fast at 1 or 2 working days, depending on whether or not you take the UV spot. More complex designs with die cutting or folding etc. cost more and take longer.
As mentioned they do loads of other printing services, so do check them out. I have ordered many times from them and always found their work exemplary.
