Hello,
About the production of the deck ,I had found 3 company(USPS,prime,a Taiwan company which can print the deck with a very good quality.But I cannot decided which company is the most suitable .I asking for suggestion of which type of company is suitable to use.
You should do some reading up on this - there's an old expression about how opinions are like a$$holes - everyone has one, but most of them stink!
Seriously, though, USPC is the market's 800-pound gorilla, the Microsoft or Google of playing cards. A majority of collectors will collect only USPC-made decks, and many of those stick exclusively to the Bicycle brand name and nothing else.
But, having said that, just because they're the 800-pound gorilla, that doesn't make them the only game in town. They got there for a reason, and that was consistent quality of product. You would need to find a company that could at least meet if not exceed that level of quality, and you'd have to promote the hell out of it. When Lawrence Sullivan released the Legends deck, a non-USPC deck he had made with an unknown printer in Taiwan, he sent advance copies of the decks to a group of people known for being respected for their opinions for the purposes of letting them review the cards, see how they perform and talk amongst the community about them. His Legends decks went on to become a huge success, a very quick sell-out. The quality was up there and the cards were very unique not just in handling but in the additional magic-related features he included in the design, making them in high demand for the low price he was selling them for. He could afford to undercut the price of most USPC-made custom decks because his printer didn't charge the same high rates - but it was NOT the price alone that made that deck a hit.
Find out just what these other companies can produce. Obtain samples from them, see how they perform compared to something like a pack of Bicycle Masters (they make for a good baseline deck for how well a custom deck should perform). If they can't beat a pack of Masters, they're not likely to gain enough traction in the market no matter how hard you promote them. But if they can, well...now the uphill battle begins. Compare price with USPC, minimum print run size, additional features (things like metallic inks, embossed and foiled boxes, etc.) and see how it all stacks up. If you find that the stars align just right and you can make a go of it, now you have to find ways to get this deck into the hearts and minds of the card-buying community. There's no one fixed formula for that, but shooting a video of a cardist performing with one of the sample decks could help significantly, as well as getting people to evaluate them. It's easier to do this with a self-funded deck, since you can have decks printed and hand out samples of your own work, but it's more risky and most people simply don't have the funds for it. You will need to go out there, kissing babies and shaking hands, making everyone know what your deck is and what it can do, especially if you're planning on a Kickstarter project to get it off the ground.
To put it simply, it's not for the faint of heart to use an unknown printer to do the job. For better or worse, most projects are made with USPC, especially those that aren't privately funded.
The only way you could easily get away with using another printer and be a success at it is if you're making an art deck, something that's created more for its attractiveness than for its performance characteristics. With a deck like that, it's not mandatory to get the best print job in terms of performance, because you really want the best print job in terms of faithful reproduction of your images, making them look brilliant and beautiful - AND you'll want a company that will let you make a really short print run that won't cost too much per deck, because you'll be getting a much smaller number of backers. Many decks have taken this route to success.
