• OG Applications do not allow for proper support of: 1) Color, 2) Page Integrity, 3) Prepress, 4) Graphics Handling, 5) Preflight, 6) Save & Package, and 7) Image Creation.
  
  
• Additional "quirks" cause additional problems but can not be conclusively identified.

• OG applications use the RGB color space. Print publishing uses CMYK or Spot colors exclusively.
  
  
• Toners and/or dyes in desktop printers achieve a greater color gamut than offset printing. Therefore, desktop color printers can achieve better results from OG files than the high-end output devices used by commercial printers.
  
  
• Because most OG users print to desktop printers not high-end devices, the OG community does not have to worry about the variables involved in offset printing (e.g., crop marks, bleeds, trapping, color separation).
  
  
• Vendors will not support OG files if they cannot make money off of OG files. Most vendors have not yet figured out effective methods of handling OG files.
  
  
• Because OG apps use RGB colors, conversion to CMYK in commercial offset will result in unstable colors and shifts will occur. CMYK color can be corrected but at significant expense and only by "better" vendors.
  
  
• The RGB Black in most OG apps will not convert correctly to 100% K in commercial offset. Therefore, text and images that should be 100% black will often contain 100% C, M, & Y, but the K plate will be blank. This error can be corrected, but at significant expense and only by "better" vendors.
  
  
• The prepress industry, with a few exceptions, has not adequately compensated for color OG files in a high-end prepress environment.
  

• Layout in OG applications is usually based on the metrics of the printer connected to the users computer.
  
  
• OG files typically reflow when output at high resolution on PostScript devices.
  
  
• Fonts must be provided to insure page integrity.
  
  
• The process of printing OG files to a desktop printer is more automated and cleaner than commercial offset printing.

• Due to technology, common prepress production issues are non-issues in a desktop color environment.
  
  
• The commercial offset printing industry has special needs such as bleeds, trim marks, trapping, and color separation.
  
  
• OG applications do not provide for common prepress needs such as bleeds, trim marks, trapping, and color separation.
  
  
• OG files require special handling to add these prepress requirements.
  
  
• Not all vendors can handle this extra work. Those that can will charge extra.

• The printing industry supports .TIFF and .EPS only.
  
  
• OG files do not support .TIFF or .EPS in an appropriate manner.
  
  
• OG files typically embed graphics. Embedding graphics makes prepress more difficult and expensive.
  
  
• Embedding graphics causes potential RIP errors.
  
  
• OG applications do not provide for graphic "link" information.
  

• Preflight is a requirement in all GPO contracts.
  
  
• OG files do not provide internal preflight tools.
  
  
• Third party utilities (e.g., FlightCheck or Preflight Pro) do not support native OG applications.
  
  
• Vendors cannot fulfill the preflight requirement when OG files are used.
  
  
• OG applications do not automatically collect necessary elements (e.g., layout, fonts and graphics).
  
  
• Users must manually collect necessary elements.
  
  
• Collecting all necessary elements is time consuming, confusing and is rarely done correctly.
  

• Graphics should not be created in OG applications. This includes charts and graphs in Excel.
  
  
• OG applications fail to export .TIFF or .EPS files.
  
  
• Color issues exist in OG created images or graphics.
  
  
• Supplied clip art is also incorrectly prepared and should not be used.
  
  
• Stroke weights are insufficient for high-end output.
