Technical Production Notes
1. For individual graphics imagesImages that contain only square pixels are provided in TIFF format.
Images involving lines or other vector-based graphics are provided
in EPS format. (Fonts have been outlined.)
1.1 Image compressionAll image files are provided in .zip format.
Use for example Stuffit Expander or ZipIt to uncompress the files.
1.2 Rescaling imagesImages should be rescaled only in a page layout program such as
QuarkXPress. Attempting to rescale in an image manipulation program such
as Photoshop will typically result in blurred edges inside the image.
The TIFFs we provide are set up so that one bitmap pixel corresponds to
exactly one cell in the underlying image. This means that these TIFFs
will often be identified by programs as low dpi images, but will print and
display correctly, with precise square cells. (Our images are encoded
so that their "dpi" gives the number of cells per inch.) Note that under
Windows XP the default Windows Picture and Fax Viewer does a form of
interpolation that makes TIF images look fuzzy when magnified.
Many of the images from A New Kind of Science contain patterns that
will moire if reduced too much. Be sure to check for moire artifacts at
the actual resolution being used for output.
1.3 Recoloring imagesThe images we provide in TIFF format can be recolored. But the images in
EPS format should not be.
(In most images, the colors chosen for different types of cells have no
intrinsic meaning, and can be chosen for best graphic effect.
However, all cells of a given type must continue to be a single color.
When recoloring, take care that captions do not refer for example to "black"
and "white" cells.)
Recoloring of TIFF images can be done using an image manipulation
program such as Photoshop.Some basic recoloring can be done
using Image-> Adjustments-> Hue/Saturation...
More sophisticated recoloring can be done for example using the Fill tool:
* Select the Fill tool:
* Make the following settings: Tolerance: 0; Anti-aliased: off; Contiguous: off
* Magnify the image until you can see individual cells
* Choose the color you want for a particular type of cell,
then click on one cell of that type with the paint bucket
* Do this for each type of cell in turn
Black-and-white TIFF images can also be recolored in a page layout program
like QuarkXPress, by changing background and foreground colors.
1.4 Images for the webUnlike for photographs with continuous color gradations, images from
A New Kind of Science can fail completely if they are scaled.
The TIFF images we provide can be cropped, but not scaled down.
To scale images up, use an image editing program such as Photoshop. Note
that these images can only be scaled by integer factors (magnifications
200%, 300%, 400%, etc.)
A convenient procedure in Photoshop is the following:
* Convert image to Indexed Color using Image > Mode > Indexed Color...
* In the Image > Image Size... dialog, rescale to 200 percent, 300 percent, etc.
* Save the resulting image as a GIF
For some purposes, you may be able to use the thumbnails from this website
as web images.
2. For book pagesBook pages are provided in EPS format.
All relevant fonts are embedded (not outlined), and can be
safely placed into most page layout programs, such as QuarkXPress and InDesign.
Once opened, the file can then be cropped to display the desired graphic.
Opening this file in a graphics program, such as Adobe Illustrator,
will likely lead to problems displaying the correct fonts, and therefore should be
avoided for most graphics.
If you need an editable version of one of the pages, We
can provide a version of this file with the fonts outlined upon request.
NOTE: Users of Corel Draw can safely open/edit the EPS files if
the "convert text to curves" option is selected when importing.
3. Direct-to-plate printingDuring the printing of A New Kind of Science we discovered a subtle
and hard-to-reproduce bug that gave rise to glitches in a few of the
rather unique images in the book.
The bug was traced to a problem in the code of a standard Adobe RIP.
The bug manifests itself in the appearance of a doubled column of cells in a
cell-based image (such as a cellular automaton).
The problem is known to occur in Creo's Prinergy 2.0.7 system. Prinergy
2.1 has the bug fixed, and Creo has told us that a patch should soon be
forthcoming for Prinergy 2.0.7.
It should be emphasized that the bug is rare: it occurred in four graphics
out of thousands in A New Kind of Science. However, we do encourage
you to check for glitches in final prints of complex images from the book.
The bug is quite transient, and rerunning with a slightly different
configuration will typically make it go away.
