white space

[Saif Eldin]

I want to know how to remove these white spaces

It's to do with display Antialiasing, check in settings that you have Precise Clipping checked under Settings > Performance. Also look at the artwork at 100% zoom.

sorry but still

This graphic has small white thin lines between the individual segments when the graphic is greatly enlarged.

It is anti-aliasing problem.

It could be that the various vector objects have been cut out exactly but there is no overlap. If you put a tiny stroke on the items lower in the layers panel that may be enough to fill in the gaps.

Are going to use your graphic in print or as a bitmap image online?

Print

Usually this shouldn't have any side effects in print.
But to be on the safe side, I'd follow @Old Bruce's advice and add a tiny "hairline" stroke of 0.25 pt, same color, centered, placed behind the fill on the objects at the bottom of the layer stack. I.e. something akin to manual trapping (as we used to in the olden days… )

As far I remember trapping usually got (auto-)set / added in the pre-press process. (e.g. to avoid white flickering of coloured text on a black background)

Wouldn't it work the same nowadays?

Although I remember the option I can't remember to have ever set or activated it for specific objects myself.

This site points to issues with trapping as function of DTP apps and a preferred, usual workflow via the RIP instead:

DTP applications such as Adobe InDesign, Scribus or QuarkXPress offer built-in trapping engines that automatically carry out trapping according to certain presets. Furthermore, most graphics programs offer the user the option of manual trapping with the options of overprinting, overfilling and underfilling, some of which are also used for certain optical effects. However, the trapping information provided in DTP applications is often not reliable as part of a production process because incorrect trapping information or data loss occurs due to incompatibilities (e.g. in the supported Postscript versions). In addition, QuarkXPress does not require the distribution of a composite file, which makes corrections to the later PDF file more difficult. Therefore, in practice, trapping is usually carried out as a last resort, i.e. in the Raster Image Processor (RIP) of the printing plate output or workflow system. This usually results in the best result. Particularly in packaging printing and when using highly opaque colors (e.g. metallic colors), trapping should be reserved for the specialists of the printing company.

I meant the olden olden days of Ulano masking films and such…
Although Freehand 9 still had a manual object based trapping overfilling feature that I used to apply occasionally. I don't remember how PM4 or QXP3/4 did it though.

thx  that was helpful
