Catalog printing is a job that is important and must be completed with careful attention to detail. Any corners cut here could result in the catalog being wasted on the viewer. These catalogs are akin to being your storefront taken into the home of the potential customer and it is an area that must display pictures that are clear and descriptions of each product that are concise, giving as much information as possible in just a few words.
The quality of the finished product is just as important as any other facet of the project because if the potential customer is unable to see a clear picture of the item they are interested in, they are unlikely to buy it. You should never entrust the completion of such a project to any company who is not well versed in the processes required to put the book onto paper.
Likewise, you should not have to spend a fortune in order to get the project done properly. It is for this reason that many such projects are being sourced to printing companies in China. Not only does their pride in a good job reflect in their work, but a significant savings can be realized over any costs that are likely to be quoted to you on the local level.
