IMPORTANCE OF RESOLUTION IN SCANNING Written by BLUR LOTERIÑA
Are you getting confused of resolution requirements for scanning? Of “high-res” your scanner offers? And do you really need it or will it just make your work slower?
Whenever we scan an image, we are very much particular with resolution and details that we get. Our ultimate goal is to have exact copy of original image. Not all scanners provide us with what we want. Although there are those which seem to give us a lot better than what we need.
A standard resolution for an image should be 300dpi (dot-per-inch) and 400dpi for images containing text. However, there are scanners that offer you greater resolutions ranging from at least 3,200 dpi up to 6,200 or 9000 dpi. But do we really need resolutions this high?
A flatbed scanner is a type of scanner that converts printed materials into digital image. It is made up of charged coupled devices or CCD. CCD is a light sensitive integrated circuit that is mounted in a stationary row. These CCDs allows light reflected from a flat art to pass over and registers presence and absence of light. So pixel is produced electronically. Pixel, from words “picture element”, is basic unit of programmable color in a computer image.
CCDs are mounted in a single row so they reflected one row of flat art at a time. The task is repeated until image is completely built. The resolution is controlled horizontally by distance between each CCD and vertically by speed of light bar and mirror that moves along length of flat art. This means that, if you want a better resolution scanner must have more CCDs and slower light bar.
Outsourcing in China: Five Basics for Reducing RiskWritten by Steve Dickinson
Many small and medium sized companies that engage in OEM manufacturing/outsourcing in China fail to take steps necessary to protect themselves. When problems arise, they can do little or nothing to protect themselves because they have no legal basis for protection. The fact is that outsourcing disputes must be resolved in China, under Chinese legal system. The Chinese legal system has improved greatly over past ten years and taking a few basic legal steps can greatly reduce your risk. The cost of such protection is modest compared to protection it will provide.
The following five basic steps will greatly reduce your problems with Chinese manufacturers, while improving your chances of recovering should any problems arise.
1. Create and properly register your intellectual property rights in United States. If you do not have a firm basis for your IP rights under U.S. law, you will have nothing to protect in China. Before you go to China, be sure your intellectual property is protected under U.S. law. Protect your brand identity by creating and registering your trademark, slogan and logo with U.S. Patent and Trademark Office. Register your important copyrights with U.S. Copyright Office. Carefully identify and protect your trade secrets, proprietary information and know how.
2. Register your trademarks in China. Registration can protect your future access to Chinese market, prevent export of counterfeit goods from China, and prevent a competitor from registering your mark in China, which would prohibit you from exporting your own product from China.
3. Use a written agreement to protect your know how and trade secrets in China. Small and medium companies usually do not have an extensive portfolio of patents. Their most valuable intangible assets typically are their know how and trade secrets, which cannot be protected by formal registration. Chinese law, however, permits companies to contractually protect their know how and trade secrets by contract. Such agreements may also address issues such as non-competition and confidentiality. Without such a written agreement, no such protection is available.
