FONTS

Vector based artwork: In theory there are many times when it is not necessary to change fonts to curves. In fact because things that can go wrong sometimes do go wrong it is wise to change all text to curves before submitting artwork.

Raster based artwork: There are no special instructions concerning fonts.


DIMENSIONS & BLEEDS

Artwork layouts that are more than 227.5" in height or in width must be reduced in size to fit 200" in the longest dimension.

The following circumstances require artwork to be created with bleeds (color beyond the finished product's edge):

  • Decals whenever the any edge of the decal is designed to align with one or more edges of the destination substrate. Except when inserting the decal within a framed, but non-framed area.
  • Decals to cut to shape after printing that have colors that align and touch any edge of the decal.

ART WORK RESOLUTIONS

  • Vector Image Artwork: Not Applicable
  • Raster Image Artwork: 150ppi @ 100% image size
high resolution printing settings can make images crisp

Making very large prints such as 8 ft. x 3 ft. banner from a very small image such as a business card will work. but the outcome will be disappointing. As a rule of thumb, examine the artwork at a zoom of 100% of the output size. If the artwork looks clean and sharp it will have a real good chance at printing clean and sharp.

Images that are all or primarily made up from vector artwork have no resolution requirements. Raster images that are embedded in vector images should be at 150 ppi minimum at 100% of the image's size.

It is a common myth that the more pixels per inch there are the more detailed and stunning the printed image will be.

In general digital artwork is made from vector based software, raster based software or a combination of vector and raster based software. Adobe Illustrator ® and Corel Draw ® are two examples of vector based software. Adobe Photoshop ® and software that accompany most digital cameras are examples of raster based software.

Vector based software creates images by utilizing mathematical formulas to calculate vector relations between objects (elements) that make up the desired image. Vector images can be scaled to very large or very small sizes without showing ragged edges.

high resolution printing settings can make images crisp

On the other hand cameras do not create vector images, they only produce raster images. A raster image is made up of small dots. Every raster image has a specific number of dots that make up columns across the width. A a specific number of dots that make rows to create the height.

It is a common myth that the more pixels per inch there are the more detailed and stunning the printed image will be. The truth is that photographs will print with plenty of visual detail and clarity with only a 150 ppi. They must be printed at higher resolutions to get the vivid detail that looks so attractive. Amazing Digital Magic only prints in higher resolutions. Vector artwork that has been change to a raster image and that has smooth curves of very straight edges on a diagonal such as the edges found in type will need a much higher resolution, especially when the finished image is large.

Vector based images do not have resolutions associated with them. However, embedded raster images need to have 150 ppi resolutions.

COLOR MANAGEMENT

  • Color Modes: CMYK
  • Internal ICC profile: Photoshop 5 default CMYK

Improper color management may produce undesirable results.

Most quality graphics design and creation software packages allow the designer to set color management properties. The color mode of the file must be set to CMYK. The internal ICC color profiles that output to the printer and to the display device must be set to Photoshop 5 default CMYK. There are usually many choices available. Some of the choices restrict the color gamut to less than the full CMYK and others set the color gamut greater than CMYK. When artwork is designed with the wrong display device color profile set, the designer may choose colors not available or may choose from a list that is less than the full spectrum available. The rules of rendering intends embedded within the design software will instruct the printer how to substitute colors not available.

In theory the image that is visible on a monitor (display device) is the same that any given printing machine will produce.

In reality things are much more complicated. We live in a world where modern manufacturing has whittled down the variation of the visual appearance of one appliance to another. This leads to a lack of visual evidence of variation, re-enforces the misconception that the performance of one appliance to the next is also lacking variation. In fact, there is significant variation and cumulative variation found in today's appliances. Modern printing machines are more accurate today than ever before and there is a continuing effort to improve the technology. The inks have received their fare share of attention over the centuries and the materials (media, including modern high tech displays) that are available are more diverse and accommodating than previously available. Yet, there is still variation from one printer to another, one material to another, one bottle of ink to the next and among display devices. Alas, there is still room and a need to improve.

Paper, plastics and other solid, non electronic media reflect light and have different capabilities for holding and absorbing ink. Display devices radiate light and of course some of them are better than others, while none are perfect. The commercial printing industry has centered around a cyan, magenta, yellow and black color system, while television and computer work in the red, green and blue arena. The short story is that there are many reasons for a computer generated image to fail during the print process. A high quality, professional color management system that incorporates custom icc profiles for all input and output devices can enhance color accuracy. A color management process for printing must include a custom icc profile for each combination of printer, inks, ink limits and media to accurately reproduce colors.

The International Color Consortium (ICC) is an organization dedicated to encouraging the use of vendor-neutral, cross platform, open color management systems. They develop standards for color management for scanners, printers, cameras and display devices. Their efforts help to reduce the variation in color from design or capture to printing or displaying.

If you want accurate color results, your printer must build in house icc profiles.

Amazing Digital Magic takes the time to develop in house custom icc color profiles. The process requires time, experience, special color management software and special measurement tools to create accurate color profiles. The time and effort produces color profiles that are more accurate than off the shelf profiles that cannot take into account the variations associated with individual printers, inks, ink limits and materials.

The first step is to linearize the cyan, magenta, yellow and black (CMYK) inks. The next step is to determine and set the maximum ink that the media is capable of holding. Too little ink and the colors will be washed out, not enough saturation. Too much ink and the images may not be as sharp as possible, or the ink will run or puddle. The proper maximum ink limit determines the maximum saturation that a given media will support. Along with the white point of the media the maximum ink limit will determine the total contrast. After determining the maximum ink limit, it is time to determine and set the ink limit for each of the colors (CMYK). It is now time to print the sample color swatches. Special software used to create the actual icc profile also creates 200-600 individual color swatches that must be printed. The software has the specifications for each of the colors, so when the colors are measured after printing by a photo spectrometer the results are compared to the specification. The software then creates an icc profile to adjust for these discrepancies.
