The present invention is to provide a ink-jet recording sheet of high ink absorptive property, high cockling resistance, high surface smoothness, low cost, and high image quality with incorporating specially designed void-forming absorptive layer whose absorptiveness is determined by a ratio of a Bristow Test value and a Cobb value. For example, the identity of an initiating end user, the identity of a targeted end user, the current activity of the targeted end user, the communication preferences of the targeted end user, information from available databases, and other available or determinable data may be used by a contact liaison to produce a recommended mode of communication. By viewing the visual representations of the audio inputs, a user is able to achieve a desired mix of signals with more accuracy and efficiency when compared with mixing based on hearing alone. The invention is characterized in that a second depth color chart generated from the original color chart by permuting at least two color channels is used in the depth dimension.
