Wireless Standards 802.11a, 802.11b/g/n, and 802.11ac

Postby claymonet112 » June 19th, 2017, 2:18 am

While 802.11b was in development, IEEE created a second extension to the original 802.11 standard called 802.11a.

Because802.11b standard gained in popularity much faster than did 802.11a, some folks believe that 802.11a was created after 802.11b. In fact, 802.11a was created at the same time. Due to its higher cost, 802.11a is usually found on business networks whereas 802.11b better serves the home market.

802.11a supports bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz. This higher frequency compared to 802.11b shortens the range of 802.11a networks. The higher frequency also means 802.11a signals have more difficulty penetrating walls and other obstructions.
I'm currently an Apple Pages user and am considering moving to Swift Publisher mainly because it seems to be able to automatically add bleed and crop marks.

In the past I've had pdf compatibility problems with print shops. The solution I found was to use a quartz filter to generate a pdf/x-3 document with CMYK colour space via the print dialog box. Crude but it seems to work in the sense that it eliminates any compatibility problems.

I'd like to understand Swift Publisher's pdf export a little better and hope you can answer these questions for me:

1. What format is the pdf exported by Swift Publisher?

2. How do you control the colour space so that your author in CMYK and the pdf exported uses CMYK?
3. How do you control the resolution of the imagery? Does it use whatever you have set up within the Swift Publisher document?

4. Are the fonts embedded?

Forgive me if the answers are already in the help pages but I couldn't find them.

hi claymonet112,
Exporting to pdf is a old and sometimes "hot" topic like this one( just an example):

in brief,
#1 SP export PDF as 1.4 PDF (so, not flatten), note that it uses Quartz PDF Context (a "feature" of OS X itself).

#2, I would say that, all colors created in SP are exported as is: strokes defines as CMYK using the CMYK sliders of Color Pane will be exported as CMYK colors
color of text: the same
fill colors of shapes: the same
So, and it 's important, it's up to you to control Rich Black's, avoiding too dense colors…
two (minor?) exceptions are : shadows and smart shapes are always exports with RGB colors
bitmaps images in CMYK remains CMYK when exported to PDF.
you can see that, opening a pdf from SP in Preview.app then displaying the inspector (Command-I)
Color Profiles are embedded
All Fonts are embedded too.
Different settings can be used with a little help from…(©Lennon/MacCartney) PDF flux created with ColorSync utility to flatten transparency or embedded specific profiles…
A last word, all these opinions/remarkscome from a user point of view, it is not necessary opinions from the editor of this application (Belight)
Even spots colors are correctly exported in PDF ! (in previous version (10.5 ?) of OS X, there was a dedicated color picker that managed Spot Colors using a little file borrow from InDesign.
Hope this help

Thank you for spending your time to me Jean-Jacques. I'd really appreciate that. Now I understood more about my own problems. Best Regard

SP5 appears to export PDF as 1.3 now (as opposed to 1.4 in SP4), at least on my Mac. A step backwards, when we need to be going forwards to address the longstanding flattening issue (blurred output when fill overlays are involved). I did post on this in some detail a while back, when I said we need 1.6 as a minimum to resolve the issue.

SP5 exports in PDF 1.4 by default

It seems that some pre-v5 files opened in v5 export as 1.3, new docs in v5 export as 1.4, although I've only tried this on a few files. Either way, export in 1.6 should be on the to-do list.
