Creative Graphic Design
HISTORY OF GRAPHIC DESIGN
Wiener Werkstätte ("Vienna Workshop")1903 — 1932Hoffmann and Kolomann Moser left the Secessionist Movement of established an association of artists and craftspeople working together to manufacture well designed household goods in the spirit of the British Arts & Crafts Movement. The early design was characterized by the great influence of Rennie Mackintosh— simplified shapes, geometric patterns, and minimal decoration. About 100 workers strove to provide good quality design to a large audience. For several years their work was sold in a shop in New York City but the cost of running the venue could not be sustained.
Science of Advertising
Psychologist and professor Walter Dill Scott introduced the study of psychology as an important element in advertising in his book The Psychology of Advertising in Theory and Practice (1902). As part of his work he questioned consumers about their reactions to various advertisements — the beginning of market research.In the advertising magazine, Printers Ink, he declared "The successful advertiser, either personally or through his advertising department, must carefully study psychology. He must understand how the human mind acts. He must know what repels and what attracts. He must know what will create an interest and what will fall flat. He must be a student of human nature and he must know the laws of the human mind."
Ernest Elmo Calkins's Business Triangle from The Art of Modern Advertising, 1905. Caukins made the link between advertising and the consumer, retailer and manufacturer."The mediums have been analyzed and classified; the goods manufactured, wrapped and named with a better idea of the purchaser's habits and needs, the consumers located and studied; their purchasing power tabulated; their shopping habits ascertained."

Computer Graphic Basics
There are two types of computer graphics – raster and vector. The raster graphic is composed of pixels and vector graphic is composed of drawing paths. It is important to understand the difference between these two types before you choose the graphics format to save the barcode image.
01. Raster Graphics
A bitmap is basically an array of pixels with values indicating the color. The bitmap sizes are defined in pixels. BMP, TIF, GIF, JPG, PNG and most other graphics formats are raster graphics. Since the sizes are measured in pixels, the print dimension depends on the resolution of the printer. BMP records every pixels in the image, so the size is very big even for small images. Other formats use compression algorithm to reduce the file size without causing great visual degrading, but remember the barcode is read by machines other than human. Overall, you need to keep the physical size unchanged otherwise you will run into problems.
For example, you generate a barcode with 1 inch wide and 0.75 inch tall. The display device usually have a dpi of 96, that translate 96 pixels per inch. If you save the image into raster graphics format, you get a bitmap array with 96 pixels wide and 72 pixels in height. When you print from a laser printer at 600 dpi, the image shrink to 1/6 of the original size and becomes un-readable. In our Barcode Studio and ActiveX control products, you can set the target resolution. Still when you copy the image form one machine to another, the same problem may arise again.
02. Vector Graphics
A vector graphic contains the drawing instructions other than the color value in pixels. In Windows platform WMF is most widely used vector graphic format that is supported by all printers. The best feature about WMF is that the dimension measures are completely device independent. It can be easily scaled without losing any characteristics( most likely you will not use the scale feature). We strongly recommend that you save your barcode image in this format. In our Barcode Studio/ActiveX products copy/paste operation is based on WMF format which preserves all the information. Other vector graphics formats include EPS (Encapsulated PostScript), SVG (Scalable Vector Graphics) format. To use EPS, you need to have a printer with postscript enabled. SVG is designed to use with World Wide Web, but they are not widely accepted. WMF is only supported in Windows platforms.
