Overview

This label class provides attributes for Bioscan 384-well plate labels, which have only a single sticker. The placement of barcode and text fields is similar to 96-well plate labels. Note that other 384-well plate labels have double stickers.

The label contains a barcode image in the middle and text on the corners.

  • The barcode image in the middle contains human barcode in code128, which is more compact and readable than code39. It needs empty space on both sides for readabilty.

  • Top-left contains date of printing

  • Bottom-left contains human barcode of the plate

  • Top-right contains the barcode of the an ancestor stock plate. For Bioscan 384-well plates, we show the first LILYS barcode, or the first LYSATE barcode; not last.

We show an ancestor stock plate barcode; not the parent. The algorithm below is generic to handle the cases when ancestor plates with the same purpose can be stock plates or non stock plates because of alternative pipeline paths and/or when ancestor plates from different paths are used together to make a plate. We show the first of the configured alternative or the first of closest stock plate ancestors.

Only Squix printers are used for printing 384-well plate labels. We do not send print requests to PMB service, instead we send them directly to SPrint service, which talks to Squix printers.
