Tiled Lattices on Fabric

Repeat printing is best understood as a kind of tiling, because fabrics are generally printed using rollers, which can be seen as large rectangles rolled into a cylinder; tiling also lends it's name to the branch of mathematics known as tessellation.

Fabric printing includes in the larger sense printed T-shirts, as well as the topic of screen printing, which in turn has an elegant interface with computers (both sytems present information on a grid).

Hawaiian shirt repeat

Fabric repeats--the stuff of print dresses, Hawaiian shirts, and boxer shorts.

The elegance of this branch of design has to be seen in a historical context. Contemporary printed fabric that's at the level of for instance, Victorian wallpaper, is usually only seen in high fashion, or in traditional cultures like Japan.

Today fabric printing is usually done by big companies whose business model apparently doesn't accommodate paying for excellent design--it's the stuff you see in yardage stores, which begins it's journey in the garment industry ('stuff' is an old word for textiles).
There's lot's of beautiful repeat artwork to be seen though, partly because it's a graphic medium that makes good book reproductions, but also because it's most natural manifestation is in tilework, which unlike fabric, lasts for thousands of years.

Block-Printed Fabric

Stamping a continuous surface using this method is like placing masonry elements--tiles, for example, alongside one another: the edges create a line, which in the case of a brick wall defines the pattern. A tiled surface has two elements: the decoration on the tiles themselves, and the line of mortar.
A brick wall is monotonously repetitive. What's needed is how to interlock the shapes in ways that don't insult the eye: muslim tile designs, for example, beautifully integrate surface motif with the tile edge pattern.

Shaped Carved block

Of course unlike tiles a block print doesn't necessarily have to line up edge-to-edge. The blocks can be moved apart so that there's empty space in between, which then behaves like the masonry grout line, a separate visual element.

What the woman in the picture is doing is a lot more efficient way to decorate a surface, however, once the individual blocks are separated by intuitive space the idea is bound to emerge, "what if the shapes were different from each other?" The answer is: they'd begin to tell a story.

Rollout of Olmec Fabric Printing Cylinder This is a rollout of an Olmec fabric printing cylinder that's thought to be the oldest evidence of written language in the new world. The image contains three separate abstract elements: the image of the bird, a banderole, a scroll-like ribbon bearing an inscription, and a glyph representing the date, 3 AJAW..
Justinian Mosaic


The name refers to the small square tiles used by the Byzantine Greeks to create the dazzling mosaics that can still be seen in Romanesque churches of that era.

The Arabs (specifically the Muslim architects of the Ottoman empire) who succeeded them needed to do something different. Islamic Law theoretically forbade the depiction of sentient life forms, so they relied on abstract design for the enrichment of the complex surfaces in their structures. Mosque of the Imam, Isfahan, IranThis was the period (shown is the Imam mosque [1611] in Esfahan, Iran) when variations of the arch and the dome were being deployed to span larger & larger spaces. A typical problem faced by Islamic architects was how to embellish a vault, a semi-spherical surface in the corner of a room. The Greeks would have simply inserted a mosaic portrait of a saint, but to cover such a surface with large tiles instead required rigorous design technique. Below is a page from the Topkapi Scroll, a kind of manual for lay
Vault-Topkapi ScrollConsider a soccer ball: it's covered with a system of pentagons surrounded by hexagons that together create a spherical surface (this is the same geometric layout as Buckminster Fuller's Geodesic Dome).
But a vault is a combination of shapes: a flat surface merging into a hemisphere, with a triangular point. Unlike the soccer ball, which consists of only two regular, naturally ocurring polygons, the vault requires a set of interlocking contrived shapes. It may be the most compelling visual statement of a mathematical system ever presented.Alhambra Tile Pattern

It's not certain that these designs were representations of a mathematical model, or were worked out by trial & error. The discussion seems to hinge on whether all 17 of the so-called wallpaper patterns can be located in pre-group theory settings such as the Alhambra Palace in Granada, Spain (above), or for that matter in other traditional systems. The overarching topic of investigation, Symmetry, is now recognised as a basic organizing principle in nature. Arab Mosaic Tiles


This tile set is a breathtaking juxtaposition of empirical math and decorative art. There's a good discussion of this layout & its implications on the site MATHEMATICA E MOSAICI ARABI. A name that always comes up in this context is that of Roger Penrose, notorious for suing the Kleenex company for using on toilet paper a proprietary tile pattern he'd discovered, despite the fact that this kind of tiling, now known as quasicrystals occurs in nature, as well as in the Islamic tile patterns we've been discussing.

Printed T-shirts

Screen printing, also known as silkscreen, or serigraphy, is a method of transfering an image by means of a stencil attached to a porous fabric stretched on a frame: color is pushed through the stencil using a squeegee, a rubber blade with a handle. It's both a commercial technique and an art form.

Long Fabric Printing Table

Silkscreened fabric used to be printed flat on long tables like the one pictured above. The important feature is an angle steel rail along one side, which acts as a baseline for aligning the screen along the axis of the fabric; screws driven into one side of the screen contact this surface when printing, and also allow for registration adjustments. The screen is stepped along the length of the fabric by contacting adjustable stops attached to the rail.

Carousel Screen Printer

A Carousel T-Shirt Printer. The screens rotate into position, pull down, print. This seems intuitively right, however commercial T-shirt printing has evolved around this machine into a mechanized system that makes it difficult to make money without printing runs of hundreds of shirts, limited to roughly a 15" design area. Nevertheless most people who take up T-shirt printing seem to assume that buying large pieces of equipment will drive their business forward .


I'm going to use this column to present an alternative, a way to keep the 'play' element in fabric design. I once found myself inside an old-style silkscreen shop where they'd set up twenty or so pallets with 2- pin registration, around a big table. One worker would put shirts on the pallets down the row, followed by others with a succession of screens, with the last person taking shirts off.
Optical BenchThe advantage of working on a tabletop is it's flexibility. One of my customers was a developer of laser devices--he used what's called an optical bench, a steel table with a grid of threaded holes in the top to set up experiments (in electronics a similar setup is called a "breadboard"). The rail along the edge of the fabric-printing table has the same function as the threaded holes: it's a way to align images in space.


A Simplified T-shirt Printer

Shown below is a version of long table adapted specifically for printing T-shirts. The main difference, aside from the palette that allows the unprinted part of the shirt to drop away from the surface (like an ironing board) is the metal tab that the screen bumps into when it slides along the long rail on the side.

A chief advantage of this layout is it's stability: the natural racking tendency, to deform into a parallelogram, of the rectangular screen is countered by the triangle formed by the three contact points. For practical purposes this means that this homemade jig is capable of more precise registration than a basic carousel shirt printing machine. This opens up the interesting possibility of doing something rarely attempted in the industry:four-color (CMYK) printing directly on fabric.

Bill of Materials

A. 3/4" plywood or particleboard. Often particleboard with formica facing is readily available. The 'culls' bin at Home Depot usually has small pieces of this type of material. Make sure it's not warped.
B. 2 X 4 ( pine, fir, redwood etc. ) Dry, straight pieces only.
C. Steel angle stock cut from bedframes, which are hardened to stay straight, which is good, but difficult to cut & drill. Use new drill bits and hacksaw blades sprayed with lots of WD40 while cutting.
Misc.1", 1 3/4" & 2" drywall screws. Drill 3/16 " pilot holes so the screws will be pulled tightly against the piece holding the screw threads.
