What does "God writes straight with crooked lines." mean ?

What does “a factor of two” mean? Given the size limitations of current LED packaging, IHS expects the rate of technological advancement with finer pixel pitches will slow significantly in the short term. And the price difference represented by a pixel pitch under 1 mm (0.04 in.) and those between 1.2 and 1.9 mm (0.05 and 0.07 in.) is almost a factor of two, so it is generally cost-prohibitive to build a large-scale video wall using the very narrowest pixel pitch LEDs.

What does "In the right hands" mean? In the right hands, screenprinting is renowned for crisp lines and compatibility with a wide variety of surfaces. Its growth today is hindered, however, by the need for a large investment in training and facilities.

What does the last sentence mean ? When designing a monument sign with tenant panels, the decision must be made as to the color of the background of the panels. White is easy, but it may not be the most complimentary to the sign’s design. When making decisions as to whether or not to have a dark background or a white background, the choice of how the logos will be rendered becomes absolutely critical. A uniform dark background can make full color logo placement impossible. Logo colors will clash not only with each other, but with the sign itself. Logos with brown text or black borders will look terrible on a dark duranodic bronze panel. White is usually a safer bet if the client insists on color logos. If not, any dark color will work splendidly as a black and white logo can be reverse weeded from the panel face, making the logo (or text) appear white in color.

What does "there are small tabletop models all the way to large-format options" mean? “You probably already have a client list that’s suitable, and the sign guy is always the go-to guy. But how much time does it take to make, or order signs?” Wilson says. “What kind of margins will you see? And what about installing? That can be tricky, especially if you’re a company that’s just done banners or traditional signage. You also have to think about deadlines. How will you get those 800 compliant signs you’ve promised out the door, without having everyone in the shop work on them at the same time? You don’t want to jeopardize your other commitments.” “With a rotary engraver, you can cut out all of your materials and prepare the sign for Braille – there are small tabletop models all the way to large-format options, so the investment can vary widely based on the size and type of rotary device you choose,” she says.

What does "a shallower depth" mean? The improvements in today’s LED modules are the driving force behind the trend to make channel letters a shallower depth.
