Air carrier captain reports overlooking the 280 knot restriction on the hhood 2 RNAV arrival to pdx....

Narrative:

We were descending out of approximately FL230 into pdx on the hhood 2 arrival; in VNAV; with all published crossing restrictions and speeds programmed into FMC. We were asked our airspeed by seattle center. I responded with 300 knots. The controller said we needed to be at 280 knots in accordance with the hhood 2 STAR. I had only shown yentl at 270 KTS as our first speed restriction. ATC said there was a prior restriction from our mach speed to 280 KTS. We eventually found this restriction on the chart. We were then told to slow to 250 KTS and switched to pdx approach and landed uneventfully. Prior to top of descent both the first officer and I separately checked the FMC and chart because of all the altitude and speed restrictions on this hhood arrival. We then briefed the chart and FMC together and neither one of us caught the 280 knot speed restriction on the chart. The placement of this 280 knot restriction on the chart is in a place that when viewed on the ipad when zoomed in a bit is out of view. Furthermore; this restriction is on the low altitude section of the chart not in the high altitude section where it's used and needs to be placed. Also I have never seen a speed restriction on any arrival stated as this one is stated. This arrival needs to have a point to be at 280 knots; or bolder; larger print of the restriction because this is not a standard speed reduction you would expect to see or be looking for on a STAR.

Title: Air Carrier Captain reports overlooking the 280 knot restriction on the HHOOD 2 RNAV arrival to PDX. This is pointed out by ATC.

Narrative: We were descending out of approximately FL230 into PDX on the HHOOD 2 arrival; in VNAV; with all published crossing restrictions and speeds programmed into FMC. We were asked our airspeed by Seattle Center. I responded with 300 knots. The controller said we needed to be at 280 knots IAW the HHOOD 2 STAR. I had only shown YENTL at 270 KTS as our first speed restriction. ATC said there was a prior restriction from our Mach speed to 280 KTS. We eventually found this restriction on the chart. We were then told to slow to 250 KTS and switched to PDX approach and landed uneventfully. Prior to top of descent both the F/O and I separately checked the FMC and chart because of all the altitude and speed restrictions on this HHOOD arrival. We then briefed the chart and FMC together and neither one of us caught the 280 knot speed restriction on the chart. The placement of this 280 knot restriction on the chart is in a place that when viewed on the iPad when zoomed in a bit is out of view. Furthermore; this restriction is on the low altitude section of the chart not in the high altitude section where it's used and needs to be placed. Also I have never seen a speed restriction on any arrival stated as this one is stated. This arrival needs to have a point to be at 280 knots; or bolder; larger print of the restriction because this is not a standard speed reduction you would expect to see or be looking for on a STAR.
